The High Energy X-ray Probe (HEX-P): Magnetars and Other Isolated Neutron Stars
J. A. J. Alford, G. A. Younes, Z. Wadiasingh +23
The hard X-ray emission from magnetars and other isolated neutron stars remains under-explored. An instrument with higher sensitivity to hard X-rays is critical to understanding th…
A search for the afterglows, kilonovae, and host galaxies of two short GRBs: GRB 211106A and GRB 211227A
M. Ferro, R. Brivio, P. D'Avanzo +30
Context: GRB 211106A and GRB 211227A are recent gamma-ray bursts (GRBs) with initial X-ray positions suggesting associations with nearby galaxies (z < 0.7). Their prompt emission c…
The cosmic build-up of dust and metals. Accurate abundances from GRB-selected star-forming galaxies at
K. E. Heintz, A. De Cia, C. C. Thöne +38
The chemical enrichment of dust and metals in the interstellar medium (ISM) of galaxies throughout cosmic time is one of the key driving processes of galaxy evolution. Here we stud…
Swift Deep Galactic Plane Survey Classification of Swift J170800402551.8 as a Candidate Intermediate Polar Cataclysmic Variable
B. O'Connor, E. Gogus, J. Hare +24
Here, we present the results of our multi-wavelength campaign aimed at classifying \textit{Swift} J170800402551.8 as part of the \textit{Swift} Deep Galactic Plane Survey (DGPS)…
The Swift Deep Galactic Plane Survey (DGPS) Phase-I Catalog
B. O'Connor, C. Kouveliotou, P. A. Evans +30
The \textit{Swift} Deep Galactic Plane Survey is a \textit{Swift} Key Project consisting of 380 tiled pointings covering 40 deg of the Galactic Plane between longitude \,…
Identification of 1RXS J165424.6-433758 as a polar cataclysmic variable
B. O'Connor, J. Brink, D. A. H. Buckley +25
We present the results of our X-ray, ultraviolet, and optical follow-up campaigns of 1RXS J165424.6-433758, an X-ray source detected with the \textit{Swift} Deep Galactic Plane Sur…
Where are the magnetar binary companions? Candidates from a comparison with binary population synthesis predictions
A. A. Chrimes, A. J. Levan, A. S. Fruchter +7
It is well established that magnetars are neutron stars with extreme magnetic fields and young ages, but the evolutionary pathways to their creation are still uncertain. Since most…
New candidates for magnetar counterparts from a deep search with the Hubble Space Telescope
A. A. Chrimes, A. J. Levan, A. S. Fruchter +5
We report the discovery of six new magnetar counterpart candidates from deep near-infrared Hubble Space Telescope imaging. The new candidates are among a sample of nineteen magneta…
A tale of two mergers: constraints on kilonova detection in two short GRBs at z0.5
B. O'Connor, E. Troja, S. Dichiara +15
We present a detailed multi-wavelength analysis of two short Gamma-Ray Bursts (sGRBs) detected by the Neil Gehrels Swift Observatory: GRB 160624A at and GRB 200522A at $z…
Measuring the Accreting Stellar and Intermediate Mass Black Hole Populations in the Galaxy and Local Group
Jonathan Grindlay, Didier Barret, Tomaso Belloni +23
The population of stellar black holes (SBHs) in the Galaxy and galaxies generally is poorly known in both number and distribution. SBHs are the fossil record of the massive stars i…
The Interplanetary Network Supplement to the BATSE 5B Catalog of Cosmic Gamma-Ray Bursts
K. Hurley, M. S. Briggs, R. M. Kippen +10
We present Interplanetary Network (IPN) localization information for 343 gamma-ray bursts observed by the Burst and Transient Source Experiment (BATSE) between the end of the 4th B…
A possible faint near-infrared counterpart to the AXP 1E~2259+58.6
F. Hulleman, A. F. Tennant, M. H. van Kerkwijk +3
We present near-infrared and optical observations of the field of the Anomalous X-ray Pulsar 1E 2259+58.6 taken with the Keck telescope. We derive a subarcsecond Chandra position a…
Discovery of the Optical Transient of the Gamma Ray Burst 990308
Bradley E. Schaefer, J. A. Snyder, J. Hernandez +53
The optical transient of the faint Gamma Ray Burst 990308 was detected by the QUEST camera on the Venezuelan 1-m Schmidt telescope starting 3.28 hours after the burst. Our photomet…
LOTIS Search for Early Time Optical Afterglows: GRB 971227
G. G. Williams, H. S. Park, E. Ables +15
We report on the very early time search for an optical afterglow from GRB 971227 with the Livermore Optical Transient Imaging System (LOTIS). LOTIS began imaging the `Original' BAT…
