Freshly ionized matter around the final Helium shell flash object V4334 Sgr (Sakurai's object)

F. Kerber, N. Pirzkal, Orsola De Marco +3

We report on the discovery of recently ionized hydrogen-deficient gas in the immediate circumstellar environment of the final helium shell flash star V4334 Sgr (Sakurai's object).…

Optical and Infrared Photometry of the Nearby Type Ia Supernova 2001el

Kevin Krisciunas, Nicholas B. Suntzeff, Pablo Candia +8

We present well sampled optical (UBVRI) and infrared (JHK) light curves of the nearby (~18.0 Mpc) Type Ia supernova SN 2001el, from 11 days before to 142 days after the time of B-b…

The high-energy gamma-ray fluence and energy spectrum of GRB 970417a from observations with Milagrito

R. Atkins, W. Benbow, D. Berley +38

Evidence of TeV emission from GRB970417a has been previously reported using data from the Milagrito detector. Constraints on the TeV fluence and the energy spectrum are now derived…

Compton Scattered Transition Radiation from Very High Energy Particles

M. L. Cherry, G. L. Case

X-ray transition radiation can be used to measure the Lorentz factor of relativistic particles. At energies approaching gamma = E/mc^2 = 10^5, transition radiation detectors (TRDs)…

Search for neutrinos from Gamma-Ray Bursts using Super-Kamiokande

Dusan Turcan, Shantanu Desai

Using the Super-Kamiokande neutrino observatory, a search was conducted for neutrinos produced in coincidence with gamma-ray bursts observed by the BATSE detector. Super-Kamiokande…

Metal Abundances and Kinematics of Bright Metal-Poor Giants Selected from the LSE Survey: Implications for the Metal-Weak Thick Disk

Timothy C. Beers, John S. Drilling, Silvia Rossi +5

We report medium-resolution (1-2 A) spectroscopy and broadband (UBV) photometry for a sample of 39 bright stars (the majority of which are likely to be giants) selected as metal-de…

Active Nuclei and Star-Forming Objects at z>2: Metallicities, Winds, and Formation Histories

W. C. Keel, W. Wu, I. Waddington +2

We present near-IR observations of AGN and star-forming objects in the field of the radio galaxy 53W002 at z=2.39. The star-forming objects, of special interest as candidate protog…

What are the Hot R Coronae Borealis Stars?

Orsola De Marco, Geoffrey C. Clayton, F. Herwig +3

We investigate the evolutionary status of four stars: V348 Sgr, DY Cen and MV Sgr in the Galaxy and HV 2671 in the LMC. These stars have in common random deep declines in visual br…

The Composition of Cosmic Rays at the Knee

S. P. Swordy, L. F. Fortson, J. Hinton +21

The observation of a small change in spectral slope, or 'knee' in the fluxes of cosmic rays near energies 10^15 eV has caused much speculation since its discovery over 40 years ago…
