Population of X-ray Sources in the Intermediate-Age Cluster NGC 3532: a Test Bed for Machine-Learning Classification
Steven Chen, Oleg Kargaltsev, Hui Yang +4
Open clusters are thought to be the birth place of most stars in the Galaxy. Thus, they are excellent laboratories for investigating stellar evolution, and X-ray properties of vari…

A Systematic View of Ten New Black Hole Spins
Paul A. Draghis, Jon M. Miller, Abderahmen Zoghbi +4
The launch of NuSTAR and the increasing number of binary black hole (BBH) mergers detected through gravitational wave (GW) observations have exponentially advanced our understandin…
NuSTAR spectral analysis beyond 79 keV with stray light
G. Mastroserio, B. W. Grefenstette, P. Thalhammer +10
Due to the structure of the NuSTAR telescope, photons at large off-axis (> 1deg) can reach the detectors directly (stray light), without passing through the instrument optics. At t…

We present the results from a coordinated XMM-Newton NuSTAR observation of the Seyfert 1 Galaxy ESO 511G030. With this joint monitoring programme, we conduct a detailed vari…
StrayCats II: An Updated Catalog of NuSTAR Stray Light Observations
R. M. Ludlam, B. W. Grefenstette, M. C. Brumback +8
We present an updated catalog of StrayCats (a catalog of NuSTAR stray light observations of X-ray sources) that includes nearly 18 additional months of observations. StrayCats v2 h…
Black holes: Timing and spectral properties and evolution
Emrah Kalemci, Erin Kara, John A. Tomsick
We review the timing and spectral evolution of black hole X-ray binary systems, with emphasis on the current accretion-ejection paradigm. When in outburst, stellar mass black hole…
Sensitivity of the GAPS Experiment to Low-energy Cosmic-ray Antiprotons
Field Rogers, Tsuguo Aramaki, Mirko Boezio +50
The General Antiparticle Spectrometer (GAPS) is an upcoming balloon mission to measure low-energy cosmic-ray antinuclei during at least three ~35-day Antarctic flights. With its la…
Soft gamma-ray polarimetry with COSI using maximum likelihood analysis
John A. Tomsick, Alexander Lowell, Hadar Lazar +2
Measurements of the linear polarization of high-energy emission from pulsars, accreting black holes, and gamma-ray bursts (GRBs) provide an opportunity for constraining the emissio…
Exploring the MeV Sky with a Combined Coded Mask and Compton Telescope: The Galactic Explorer with a Coded Aperture Mask Compton Telescope (GECCO)
Elena Orlando, Eugenio Bottacini, Alexander Moiseev +33
The sky at MeV energies is currently poorly explored. Here we present an innovative mission concept that builds on and improves past and currently proposed missions at such energie…
Orbital decay in M82 X-2
Matteo Bachetti, Marianne Heida, Thomas Maccarone +21
M82 X-2 is the first pulsating ultraluminous X-ray source (PULX) discovered. The luminosity of these extreme pulsars, if isotropic, implies an extreme mass transfer rate. An altern…
Unveiling the Fermi Bubbles origin with MeV photon telescopes
Michela Negro, Henrike Fleischhack, Andreas Zoglauer +2
The Fermi Bubbles (FB) are a pair of large-scale ellipsoidal structures extending above and below the Galactic plane almost symmetrically aligned with the Galactic Center. After mo…
Spectral and Timing Analysis of NuSTAR and Swift/XRT Observations of the X-Ray Transient MAXI J0637-430
Hadar Lazar, John A. Tomsick, Sean N. Pike +10
We present results for the first observed outburst from the transient X-ray binary source MAXI J0637-430. This study is based on eight observations from the Nuclear Spectroscopic T…
Study of in the COSI 2016 superpressure balloon flight

The Compton Spectrometer and Imager (COSI) is a balloon-borne compact Compton telescope designed to survey the -ray sky from 0.2 to 5 MeV. COSI's wide field-of-view (FOV) and ex…
The X-ray binary population in the Galactic Center revealed through multi-decade observations
Kaya Mori, Charles J. Hailey, Theo Y. E. Schutt +6
We present an investigation of the quiescent and transient X-ray binaries (XRBs) of the Galactic Center (GC). We extended our Chandra analysis of the non-thermal X-ray sources, loc…
Discovery and confirmation of the shortest gamma ray burst from a collapsar
Tomas Ahumada, Leo P. Singer, Shreya Anand +54
Gamma-ray bursts (GRBs) are among the brightest and most energetic events in the universe. The duration and hardness distribution of GRBs has two clusters, now understood to reflec…
