Fermi LAT Observations of the Vela Pulsar
A. A. Abdo
The Vela pulsar is the brightest persistent source in the GeV sky and thus is the traditional first target for new gamma-ray observatories. We report here on initial Fermi Large Ar…
Supergiant Temperatures and Linear Radii from Near-Infrared Interferometry

We present angular diameters for 42 luminosity class I stars and 32 luminosity class II stars that have been interferometrically determined with the Palomar Testbed Interferometer.…
GRB 080503: Implications of a Naked Short Gamma-Ray Burst Dominated by Extended Emission
D. A. Perley, B. D. Metzger, J. Granot +22
We report on observations of GRB 080503, a short gamma-ray burst with very bright extended emission (about 30 times the gamma-ray fluence of the initial spike) in conjunction with…
Interferometric Studies of the extreme binary, Aurigae: Pre-eclipse Observations
R. Stencel, M. Creech-Eakman, A. Hart +3
We report new and archival K-band interferometric uniform disk diameters obtained with the Palomar Testbed Interferometer for the eclipsing binary star Aurigae, in advance of t…
An AKARI Search for Intracluster Dust of Globular Clusters
N. Matsunaga, H. Mito, Y. Nakada +7
We report the observations of 12 globular clusters with the AKARI/FIS. Our goal is to search for emission from the cold dust within clusters. We detect diffuse emissions toward NGC…
Cometary Astropause of Mira Revealed in the Far-Infrared
Toshiya Ueta
Evolved mass-losing stars such as Mira enrich the interstellar medium (ISM) significantly by their dust-rich molecular wind. When these stars move fast enough relative to the ISM,…
AKARI/FIS Mapping of the ISM-Wind Bow Shock around Alpha Ori
Toshiya Ueta, Hideyuki Izumiura, Issei Yamamura +7
We present 10' x 50' scan maps around an M supergiant Alpha Ori at 65, 90, 140 and 160 microns obtained with the AKARI Infrared Astronomy Satellite. Higher spatial resolution data…
Pre-launch estimates for GLAST sensitivity to Dark Matter annihilation signals
E. A. Baltz, B. Berenji, G. Bertone +25
We investigate the sensitivity of the Gamma-ray Large Area Space Telescope (GLAST) to indirectly detect weakly interacting massive particles (WIMPs) through the -ray signal that…
Measurement of cosmic-ray low-energy antiproton spectrum with the first BESS-Polar Antarctic flight
K. Abe, H. Fuke, S. Haino +27
The BESS-Polar spectrometer had its first successful balloon flight over Antarctica in December 2004. During the 8.5-day long-duration flight, almost 0.9 billion events were record…
HST Snapshot Survey of Post-AGB Objects
N. Siodmiak, M. Meixner, T. Ueta +3
The results from a Hubble Space Telescope (HST) snapshot survey of post-AGB objects are shown. The aim of the survey is to complement existing HST images of PPN and to connect vari…
Kinematics and H_2 morphology of the multipolar Post-AGB star IRAS 16594-4656
G. C. Van de Steene, T. Ueta, P. A. M. van Hoof +2
context: The spectrum of IRAS 16594-4656 shows shock excited H_2 emission and collisionally excited emission lines such as[O I],[C I],and [Fe II]. aim: The goal is to determine the…
The Afterglows of Swift-era Gamma-Ray Bursts. I. Comparing pre-Swift and Swift era Long/Soft (Type II) GRB Optical Afterglows
D. A. Kann, S. Klose, B. Zhang +73
We have gathered optical photometry data from the literature on a large sample of Swift-era gamma-ray burst (GRB) afterglows including GRBs up to September 2009, for a total of 76…
A celestial gamma-ray foreground due to the albedo of small solar system bodies and a remote probe of the interstellar cosmic ray spectrum
Igor V. Moskalenko, Troy A. Porter, Seth W. Digel +2
We calculate the gamma-ray albedo flux from cosmic-ray (CR) interactions with the solid rock and ice in Main Belt asteroids (MBAs), Jovian and Neptunian Trojan asteroids, and Kuipe…
Swift captures the spectrally evolving prompt emission of GRB 070616
R. L. C. Starling, P. T. O'Brien, R. Willingale +14
The origins of Gamma-ray Burst prompt emission are currently not well understood and in this context long, well-observed events are particularly important to study. We present the…
The Dual-Axis Circumstellar Environment of the Type IIn Supernova 1997eg
Jennifer L. Hoffman, Douglas C. Leonard, Ryan Chornock +3
We present multi-epoch spectral and spectropolarimetric observations of the Type IIn supernova (SN) 1997eg that indicate the presence of a flattened disk-like concentration of circ…
Three Years of Mira Variable CCD Photometry: What Has Been Learned?
D. E. Mais, D. Richards, R. E. Stencel
The subject of micro-variability among Mira stars has received increased attention since DeLaverny et al. (1998) reported short-term brightness variations in 15 percent of the 250…
GRB 061121: Broadband spectral evolution through the prompt and afterglow phases of a bright burst
K. L. Page, R. Willingale, J. P. Osborne +33
Swift triggered on a precursor to the main burst of GRB 061121 (z=1.314), allowing observations to be made from the optical to gamma-ray bands. Many other telescopes, including Kon…
HST/NICMOS Imaging Polarimetry of Proto-Planetary Nebulae II: Macro-morphology of the Dust Shell Structure via Polarized Light
Toshiya Ueta, Koji Murakawa, Margaret Meixner
The structure of the dusty circumstellar envelopes (CSEs) of proto-planetary nebulae (PPNs) reveals the mass-loss history of these sources and how such histories may differ for ell…
