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…
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…
