The FIRST Bright Quasar Survey. II. 60 Nights and 1200 Spectra Later
R. L. White, R. H. Becker, M. D. Gregg +11
We have used the VLA FIRST survey and the APM catalog of the POSS-I plates as the basis for constructing a new radio-selected sample of optically bright quasars. This is the first…
The Hubble Deep Field South - STIS Imaging
J. P. Gardner, S. A. Baum, T. M. Brown +18
We present the imaging observations made with the Space Telescope Imaging Spectrograph of the Hubble Deep Field - South. The field was imaged in 4 bandpasses: a clear CCD bandpass…
Prompt and delayed emission properties of Gamma-Ray Bursts observed with BeppoSAX
F. Frontera, L. Amati, E. Costa +14
We investigated the spectral evolution in the 2--700 keV energy band of Gamma-Ray Bursts (GRBs) detected by the Gamma-Ray Burst Monitor (GRBM) and localized with the Wide Field Cam…
A New View on Young Pulsars in Supernova Remnants: Slow, Radio-quiet, & X-ray Bright
E. V. Gotthelf, G. Vasisht
We propose a simple explanation for the apparent dearth of radio pulsars associated with young supernova remnants (SNRs). Recent X-ray observations of young remnants have revealed…
Observations of 20 millisecond pulsars in 47 Tucanae at 20 cm
F. Camilo, D. R. Lorimer, P. Freire +2
We have used a new observing system on the Parkes radio telescope to carry out a series of pulsar observations of the globular cluster 47 Tucanae at 20-cm wavelength. We detected a…
A Multi-Component Measurement of the Cosmic Ray Composition Between 10^{17} eV and 10^{18} eV
T. Abu-Zayyad, K. Belov, D. J. Bird +45
The average mass composition of cosmic rays with primary energies between eV and eV has been studied using a hybrid detector consisting of the High Resolution Fly…
Photometric Redshifts Of Starburst Galaxies
Charles T. Liu
Although starburst galaxies have relatively flat spectral energy distributions, their strong optical emission lines and near-UV continua make it very feasible to estimate their red…
Quasars As Absorption Probes Of The Hubble Deep Field
Charles Liu, Cathy Petry, Chris Impey +1
We present a catalog of 30 QSOs and their spectra, in the square degree of sky centered on the northern Hubble Deep Field. These QSOs were selected by multicolor photometry and sub…
Chemical Abundances and the Metagalactic Radiation Field at High Redshift
Daniel Wolf Savin
We have carried out model calculations of the photoionized intergalactic medium (IGM) to determine the effects on the predicted ionic column densities due to uncertainties in the p…
COMPTEL limits on 26Al 1.809 MeV line emission from gamma^2 Velorum
U. Oberlack, U. Wessolowski, R. Diehl +7
The Wolf-Rayet binary system gamma^2 Vel (WR 11} is the closest known Wolf-Rayet (WR) star. Recently, its distance has been redetermined by parallax measurements with the HIPPARCOS…
The Structure of the Circumstellar Envelope of SN 1987A
Arlin P. S. Crotts
The volume around the SN 1987A contains a variety of structures, not just the three rings glowing in recombination lines. Many of these are revealed by light echoes, so are mapped…
MEGA, a Wide-Field Survey of Microlensing in M31
A. P. S. Crotts, R. Uglesich, G. Gyuk
We detail how microlensing internal to M31 could be used to test whether a large fraction of the matter in spiral galaxy haloes is composed of dark objects with masses comparable t…
A New Pulsar/SNR Pair: AX J1845-0258 in G29.6+0.1
E. V. Gotthelf, G. Vasisht, K. Torii +1
We present a follow-up X-ray and radio study of the field containing the 7-s X-ray pulsar AX J1845-0258, the serendipitous ASCA source whose characteristics are found to be similar…
The End of the Lines for OX 169: No Binary Broad-Line Region
J. P. Halpern, M. C. Eracleous
We show that unusual Balmer emission line profiles of the quasar OX 169, frequently described as either self-absorbed or double peaked, are actually neither. The effect is an illus…
FIRST Bent-Double Radio Sources: Tracers of High-Redshift Clusters
E. L. Blanton, M. D. Gregg, D. J. Helfand +2
Bent-double radio sources can act as tracers for clusters of galaxies. We present imaging and spectroscopic observations of the environments surrounding ten of these sources (most…
Energy Estimation of UHE Cosmic Rays using the Atmospheric Fluorescence Technique
C. Song, Z. Cao, B. R. Dawson +3
We use the CORSIKA air shower simulation program to review the method for assigning energies to ultra-high energy (UHE) cosmic rays viewed with the air fluorescence technique. This…
A New Cosmological Model of Quintessence and Dark Matter
Varun Sahni, Limin Wang
We propose a new class of quintessence models in which late times oscillations of a scalar field give rise to an effective equation of state which can be negative and hence drive t…
A supernova remnant coincident with the slow X-ray pulsar AX J1845-0258
B. M. Gaensler, E. V. Gotthelf, G. Vasisht
We report on Very Large Array observations in the direction of the recently-discovered slow X-ray pulsar AX J1845-0258. In the resulting images, we find a 5-arcmin shell of radio e…
Testing linear-theory predictions of galaxy formation
Ben Sugerman, F. J. Summers, Marc Kamionkowski
The angular momentum of galaxies is routinely ascribed to a process of tidal torques acting during the early stages of gravitational collapse, and is predicted from the initial mas…
RX J1624.9+7554: A new X-ray transient AGN
D. Grupe, H. -C. Thomas, K. M. Leighly
We report the discovery of a new X-ray transient AGN, RX J1624.9+7554. This object appeared to be bright in the ROSAT All-Sky Survey, but had turned off in two pointed observations…
Binary events and extragalactic planets in pixel microlensing
Edward A. Baltz, Paolo Gondolo
Pixel microlensing, i.e. gravitational microlensing of unresolved stars, can be used to explore distant stellar systems, and as a bonus may be able to detect extragalactic planets.…
The FIRST Efficient Gravitational Lens Survey
J. Lehar, A. Buchalter, R. McMahon +4
We have found three gravitational lenses (two are new) by observing 34 likely FIRST radio lobes with APM galaxy counterparts. We expect to find such lenses in over the nex…
Evidence of 10-100 TeV Electrons in Supernova Remnants
G. E. Allen, E. V. Gotthelf, R. Petre
Analyses of the X-ray data of the five young shell-type supernova remnants Cas A, Kepler, Tycho, SN 1006, and RCW 86 suggest that some of the X-ray emission of these sources is non…
A case devoid of bias: ORS voids vs. IRAS voids
Hagai El-Ad, Tsvi Piran
We present a comparison between the voids in two nearly all sky redshift surveys: the ORS and the IRAS 1.2 Jy. While the galaxies in these surveys are selected differently and thei…
