Time-evolution of Peak Energy and Luminosity Relation within Pulses for GRB 061007: Probing Fireball Dynamics
Masanori Ohno, Kunihito Ioka, Kazutaka Yamaoka +3
We perform a time-resolved spectral analysis of bright, long Gamma-ray burst GRB 061007 using Suzaku/WAM and Swift/BAT. Thanks to the large effective area of the WAM, we can invest…
AGB Stars in the Fornax Dwarf Spheroidal Galaxy
Patricia A. Whitelock, John W. Menzies, Michael W. Feast +3
We report on a multi-epoch study of the Fornax dwarf spheroidal galaxy, made with the Infrared Survey Facility, over an area of about 42'x42'. The colour-magnitude diagram shows a…
Study of the Spectral and Temporal Characteristics of X-Ray Emission of the Gamma-Ray Binary LS 5039 with Suzaku
T. Takahashi, T. Kishishita, Y. Uchiyama +6
We report on the results from Suzaku broadband X-ray observations of the galactic binary source LS5039. The Suzaku data, which have continuous coverage of more than one orbital per…
Photometric redshift accuracy in AKARI Deep Surveys
M. Negrello, S. Serjeant, C. Pearson +11
We investigate the photometric redshift accuracy achievable with the AKARI infrared data in deep multi-band surveys, such as in the North Ecliptic Pole field. We demonstrate that t…
Resolved 24.5 micron emission from massive young stellar objects
W. J. de Wit, M. G. Hoare, T. Fujiyoshi +8
Massive young stellar objects (MYSO) are surrounded by massive dusty envelopes. Our aim is to establish their density structure on scales of ~1000 AU, i.e. a factor 10 increase in…
Suzaku Observations of Extreme MeV Blazar SWIFT J0746.3+2548
Shin Watanabe, Rie Sato, Tadayuki Takahashi +8
We report the Suzaku observations of the high luminosity blazar SWIFT J0746.3+2548 (J0746) conducted in November 2005. This object, with z = 2.979, is the highest redshift source o…
