The discovery outburst of the X-ray transient IGR J17497-2821 observed with RXTE and ATCA
Jerome Rodriguez, Marion Cadolle Bel, John A. Tomsick +4
We report the results of a series of RXTE and ATCA observations of the recently-discovered X-ray transient IGR J17497-2821. Our 3-200 keV PCA+HEXTE spectral analysis shows very lit…
Discovery of a New X-Ray Burst/Millisecond Accreting Pulsar HETE J1900.1-2455
M. Suzuki, N. Kawai, T. Tamagawa +16
A class of low-mass X-ray binary sources are known to be both X-ray burst sources and millisecond pulsars at the same time. A new source of this class was discovered by High Energy…
MAXIPOL: Cosmic Microwave Background Polarimetry Using a Rotating Half-Wave Plate
B. R. Johnson, J. Collins, M. E. Abroe +20
We discuss MAXIPOL, a bolometric balloon-borne experiment designed to measure the E-mode polarization of the cosmic microwave background radiation (CMB). MAXIPOL is the first bolom…
Nearby Supernova Factory Observations of SN 2006D: On Sporadic Carbon Signatures in Early Type Ia Supernova Spectra
The Nearby Supernova Factory, :, R. C. Thomas +27
We present four spectra of the Type Ia supernova (SN Ia) 2006D extending from -7 to +13 days with respect to B-band maximum. The spectra include the strongest signature of unburned…
The Giant Flare of December 27, 2004 from SGR 1806-20
Steven E. Boggs, A. Zoglauer, E. Bellm +5
The giant flare of December 27, 2004 from SGR 1806-20 represents one of the most extraordinary events captured in over three decades of monitoring the gamma-ray sky. One measure of…
Swift observations of GRB050904: the most distant cosmic explosion ever observed
G. Cusumano, V. Mangano, G. Chincarini +30
Swift discovered the high redshift (z=6.29) GRB050904 with the Burst Alert Telescope (BAT) and began observing with its narrow field instruments 161 s after the burst onset. This g…
MAXIPOL: Data Analysis and Results
J. H. P. Wu, J. Zuntz, M. E. Abroe +17
We present results from and the analysis of data from MAXIPOL, a balloon-borne experiment designed to measure the polarization in the Cosmic Microwave Background (CMB). MAXIPOL is…
Search for polarization from the prompt gamma-ray emission of GRB 041219a with SPI on INTEGRAL
E. Kalemci, S. E. Boggs, C. Kouveliotou +2
Measuring the polarization of the prompt gamma-ray emission from GRBs can significantly improve our understanding of both the GRB emission mechanisms, as well as the underlying eng…
The Orbit of the Eclipsing X-ray Pulsar EXO 1722-363
Thomas W. J. Thompson, John A. Tomsick, J. J. M. in 't Zand +2
With recent and archival Rossi X-Ray Timing Explorer (RXTE) X-ray measurements of the heavily obscured X-ray pulsar EXO 1722-363 (IGR J17252-3616), we carried out a pulse timing an…
The Advanced Compton Telescope Mission
Steven E. Boggs, James Kurfess, James Ryan +30
The Advanced Compton Telescope (ACT), the next major step in gamma-ray astronomy, will probe the fires where chemical elements are formed by enabling high-resolution spectroscopy o…
First Surface-resolved Results with the IOTA Imaging Interferometer: Detection of Asymmetries in AGB stars
S. Ragland, W. A. Traub, J. -P. Berger +20
We have measured non-zero closure phases for about 29% of our sample of 56 nearby Asymptotic Giant Branch (AGB) stars, using the 3-telescope Infrared Optical Telescope Array (IOTA)…
Nearby Supernova Factory Observations of SN 2005gj: Another Type Ia Supernova in a Massive Circumstellar Envelope
The Nearby Supernova Factory Collaboration, G. Aldering, P. Antilogus +24
We report Nearby Supernova Factory observations of SN 2005gj, the second confirmed case of a "hybrid" Type Ia/IIn supernova. Our early-phase photometry of SN 2005gj shows that the…
Imaging extended sources with coded mask telescopes: Application to the INTEGRAL IBIS/ISGRI instrument
Renaud Matthieu, Alexandra Gros, François Lebrun +4
Context. In coded mask techniques, reconstructed sky images are pseudo-images: they are maps of the correlation between the image recorded on a detector and an array derived from t…
When Do Internal Shocks End and External Shocks Begin? Early-Time Broadband Modelling of GRB 051111
N. R. Butler, W. Li, D. Perley +18
Even with the renaissance in gamma-ray burst (GRB) research fostered by the Swift satellite, few bursts have both contemporaneous observations at long wavelengths and exquisite obs…
An Optically Dark GRB Observed by HETE-2: GRB 051022
Yujin E. Nakagawa, Atsumasa Yoshida, Satoshi Sugita +33
GRB 051022 was detected at 13:07:58 on 22 October 2005 by HETE-2. The location of GRB 051022 was determined immediately by the flight localization system. This burst contains multi…
