Abstract

We apply three data science techniques, Nonnegative Matrix Factorization (NMF), Principal Component Analysis (PCA) and Independent Component Analysis (ICA), to simulated X-ray energy spectra of a particular class of super-massive black holes. Two competing physical models, one whose variable components are additive and the other whose variable components are multiplicative, are known to successfully describe X-ray spectral variation of these super-massive black holes, within accuracy of the contemporary observation. We hope to utilize these techniques to compare the viability of the models by probing the mathematical structure of the observed spectra, while comparing advantages and disadvantages of each technique. We find that PCA is best to determine the dimensionality of a dataset, while NMF is better suited for interpreting spectral components and comparing them in terms of the physical models in question. ICA is able to reconstruct the parameters responsible for spectral variation. In addition, we find that the results of these techniques are sufficiently different that applying them to observed data may be a useful test in comparing the accuracy of the two spectral models., Physical characteristics: Original contains color illustrations, 形態: カラー図版あり

Abstract

We report the X-ray study of five brightest ultraluminous X-ray sources (ULXs) in the interacting galaxy system NGC4490 and NGC4485 using the archived data from three Chandra and one XMMNewton observations. To investigate spectral variations of these ULXs, we plotted their disk luminosities against the innermost disk temperatures estimated via the multi-color disk model. We found that the observed spectral variations are classified into two types; one indicating a power-law relation between the luminosity and the innermost disk temperature and the other without such a relation. The latter type shows flux changes more than an order. We discuss spectral state changes for individual sources., Meeting Information: The 3rd Suzaku international Conference "Energetic Cosmos : from Suzaku to ASTRO-H" (June 29-July 2, 2009.

Abstract

We re-analyzed the Suzaku data of the black hole binary GX 339-4, obtained in 2007 February. We observe an Fe-K emission line in the XIS spectrum, but the data do not require its extremely relativistic broadening claimed by Miller et al. (2008). Furthermore, the disk emission seen in the softest end of the continuum yields R(sub in)/ R(sub g) approximately 11, assuming a black-hole mass of 7 solar masses and a distance of 8 kpc. Thus, the disk is likely to be truncated at > 6 R(sub g), and hence the Suzaku data can be fully explained in terms of a non-rapidly-spinning black hole (Yamada, Makishima et al. 2009, ApJL, submitted). The above results were obtained using the XIS, HXD-PIN, and HXD-GSO data covering 0.5-300 keV, in which the XIS data were carefully corrected for event pile-up effects and telemetry saturation. The source was found in the "Very High" state, with a 0.5-200 keV luminosity of 3.8 x 10(sup 38) erg/s/cm(sup 2). We successfully reproduced the wide-band spectrum as a combination of a power-law with gamma approximately 2.6, a disk blackbody with T(sub in) approximately 0.7 keV, a narrow iron line with an EW approximately 40 eV, and a reflection with Omega / 2 pi approximately 0.6. In short, we need a particular caution in quoting a disk penetration down to approximately R(sub g)., Meeting Information: The 3rd Suzaku international Conference "Energetic Cosmos : from Suzaku to ASTRO-H" (June 29-July 2, 2009.

With the advance of digital technologies, huge amounts of astronomical data are being produced today by groundbased observatories and astronomical satellites. In order to efficiently extract scientific information from these data, a convenient method to visualize a large amount of astronomical data is required. Meanwhile, recent digital planetarium technologies allow us to display high resolution images on a planetarium dome. Thus, in this paper, we have investigated possibilities to use digital planetarium as a tool to visualize a large amount of astronomical data. We have made a digital planetarium program using actual astronomical observation data, mainly from JAXA's scientifi c satellites. Such a planetarium program also can provide educational, public outreach and entertainment purposes., デジタル技術の進展に伴い，今日，大量の天文観測データが地上の天文台や天文衛星から生み出されつつある．これらの大量データから適切な科学的情報を引き出すために，データを効率よく可視化する方法が望まれている．一方，デジタル技術の進歩により，近年，高精度のイメージをプラネタリウムで投影することが可能になってきている．そこで，この論文では，大規模な天文データの可視化のツールとしてデジタルプラネタリウムを利用する可能性について考察した．実際に，主にJAXAの科学衛星による観測データを用いたプラネタリウム番組を製作したので，その手法について報告する．そのようなプラネタリウム番組は可視化のツールとして使えるだけではなく，教育，アウトリーチ，娯楽の目的も果たすことができる。, Physical characteristics: Original contains color illustrations, 形態: カラー図版あり

Abstract

MAXI(Monitor of All-sky X-ray Image) は2009 年8 月から「きぼう」船外実験プラットフォーム上で観測を続けているX 線全天モニタである．MAXI には2 つの主要な役割があり，1 つはX 線突発変動天体の速報，もう1 つは長期にわたる全天のX 線による定常的な観測である．MAXI はISS の通信環境により，観測時間の70% はリアルタイムにデータを取得できる．MAXI は，リアルタイムデータを効率良く扱うため，MAXI-DB という地上システムを構築し，それらを利用してこれまでの3 年間の観測で150 件以上ものX 線天体の変動現象に関する観測速報を行った．MAXI の観測データには多くの天体に関する様々な科学情報が含まれるため，データを全世界の科学者に利用しやすい形式で提供することは重要である．我々は段階的にデータ公開を実現してきており，現在までに300 程度のカタログ天体の日々の画像，ライトカーブ，エネルギースペクトルデータや，ユーザーが任意に入力し位置/ 時刻に対応したデータ( オンデマンドデータ) を公開している．MAXI のデータは時間/ 空間方向で複雑に入り組んでいるため，1 日毎に全データを1 ファイルにアーカイブする方式では非効率で，オンデマンド公開で天体毎の解析処理の際，要求される処理時間を達成できなかった．そこで，X 線データを時刻や到来方向によって整理し，幾つかのファイルに分割し，結合する方式を使ったシステムを構築した．その結果，100 倍程度の効率化を達成することができた．, MAXI, the only all-sky X-ray monitor on the International Space Station (ISS), started observation in 2009 August. MAXI has two major objectives, 1) to issue rapid alerts of new X-ray novae/transients into astronomers worldwide and 2) to acquire long-term allsky X-ray data. Thanks to the good network connection between the ISS and the ground station, we can obtain 70% of MAXI data through the real-time communication path. We built a ground system (referred as“ MAXI-DB”) to handle real-time data efficiently; with the MAXI-DB and the alert system we issued 29150 rapid alerts in the three years since MAXI started observation. It is crucial to provide MAXI data to scientists all over the world, because MAXI data includes rich information. The MAXI data has been released to public step by step. Daily data products including images, light curves and energy spectra for 29300 pre-registered X-ray sources have been archived on the MAXI web site (http://maxi.riken.jp/top). Since the MAXI data taken by the slit-scan observation includes complex information on all-sky X-ray sources, it is not easy to collect data for a given source quickly on demand. We thus developed the MAXI on-demand archive system which sort all event data in orders of the sky region and the time. The new archive system is confirmed to process data for any celestial source 29100 times faster than the former system., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations

19. Galactic transient sources with MAXI

Author

海老沢, 研, Ebisawa, Ken, 海老沢, 研, and Ebisawa, Ken

Abstract

Thanks to its superior sensitivity, energy resolution and wide energy coverage, MAXI is expected to open a new window in the study of Galactic X-ray transients. In this paper, I selected the following eight areas in which MAXI is expected to make significant contributions to our understanding of the Galactic transient sources: (1) Detailed study of bright transients, (2) Monitor spectral variations, (3) Accretion disk spectral variation, (4) Faint transients, (5) Transient search in crowded region, (6) Supergiant fast X-ray transients, (7) Ultra-soft transients, and (8) Extragalactic stellar transients. For each area, I explain what MAXI will be able to do, in contrast to previous observations by all sky monitors., Meeting Information: Astrophysics with All-Sky X-Ray observations: 3rd International MAXI Workshop (RIKEN, 10-12 June 2008)

20. Suzaku observation of the enigmatic hard X-ray source XSS J12270-4859

Abstract

We report on the results of Suzaku and RXTE X-ray observations of XSS J12270-4859, one of the hard X-ray sources in the INTEGRAL catalogue. From optical spectroscopic characteristics and a report of putative X-ray periodicity of approximately 860 s, the object was once classified as an intermediate polar (IP). Our Suzaku observation revealed a lack of the Fe Kalpha emission in a power-law spectrum and exotic phenomena in the light curve such as (1) repetitive rapid flux amplification, (2) sudden flux declines with no periodicity, and (3) spectral hardening. We also analyzed archival RXTE data, confirming flux variations similar to those found in Suzaku, and found that the previously reported 860 s period is interpreted by semi-regularly repeated flares. These timing behaviors and the power-law spectrum suggest that XSS J12270-4859 is a low-mass X-ray binary rather than an IP. Some of the temporal characteristics are also similar to those of the type II bursters, making XSS J12270-4859 a very rare type II burster candidate., Meeting Information: The 3rd Suzaku international Conference "Energetic Cosmos : from Suzaku to ASTRO-H" (June 29-July 2, 2009.
