The Constant Evolution of the Neil Gehrels Swift Observatory: Two Decades of Operational Innovation for Time-Domain and Multi-Messenger Astrophysics
Jamie A. Kennea
The Neil Gehrels Swift Observatory has, for more than twenty years, served as NASA's premier rapid-response, multi-wavelength facility for the study of gamma-ray bursts (GRBs) and…
SXP 31.0 -- the 2025 near-Eddington double X-ray outburst after 26 years of quiescence
Malcolm J. Coe, Thomas M. Gaudin, Itumeleng M. Monageng +5
SXP 31.0 is an X-ray source in the Small Magellanic Cloud (SMC) that was first identified as a Be X-ray Binary (BeXRB) system when it went into X-ray outbusrst in 1998. It is now k…
Classification of a New X-ray Catalog of Likely Counterparts to 4FGL-DR4 Unassociated Gamma-ray Sources Using a Neural Network
Kyle D. Neumann, Abraham D. Falcone, Stephen DiKerby +5
Our survey of the fourth Large Area Telescope catalog (4FGL) unassociated gamma-ray source regions using the X-Ray Telescope (XRT) and Ultraviolet/Optical Telescop…
Comprehensive X-ray Observations of the Exceptional Ultra-long X-ray and Gamma-ray Transient GRB 250702B with Swift, NuSTAR, and Chandra: Insights from the X-ray Afterglow Properties
Brendan O'Connor, Ramandeep Gill, James DeLaunay +22
GRB 250702B is an exceptional transient that produced multiple episodes of luminous gamma-ray radiation lasting for ks, placing it among the class of ultra-long gamma-ray bur…
Identification of New Candidate Be/X-Ray Binary Systems in the Small Magellanic Cloud via Analysis of S-CUBED Source Catalog
Thomas M. Gaudin, Jamie A. Kennea, Malcolm J. Coe +1
It has long been known that a large population of Be/X-ray Binaries (BeXRBs) exists in the Milky Way's neighboring dwarf galaxy, the Small Magellanic Cloud (SMC), due to a recent p…
Multidisciplinary Science in the Multimessenger Era
Eric Burns, Christopher L. Fryer, Ivan Agullo +82
Astrophysical observations of the cosmos allow us to probe extreme physics and answer foundational questions on our universe. Modern astronomy is increasingly operating under a hol…
