A Possible X-ray and Gamma-ray Quasi-Periodic Oscillation in GRB 241030A
Noel Klingler, Cecilia Chirenti, M. Coleman Miller +2
Quasiperiodic oscillations (QPOs) in gamma-ray intensity have been reported from a few gamma-ray bursts. These QPOs could be related to fundamental frequencies in the sources, whic…
EP250827b/SN 2025wkm: An X-ray Flash-Supernova Powered by a Central Engine and Circumstellar Interaction
Gokul P. Srinivasaragavan, Dongyue Li, Xander J. Hall +100
We present the discovery of EP250827b/SN 2025wkm, an X-ray Flash (XRF) discovered by the Einstein Probe (EP), accompanied by a broad-line Type Ic supernova (SN Ic-BL) at $z = 0.119…
A carbon-rich atmosphere on a windy pulsar planet
Michael Zhang, Maya Beleznay, Timothy D. Brandt +17
A handful of enigmatic Jupiter-mass objects have been discovered orbiting pulsars. One such object, PSR\,J2322-2650b, uniquely resembles a hot Jupiter exoplanet due to its minimum…
EP250108a/SN 2025kg: A Jet-Driven Stellar Explosion Interacting With Circumstellar Material
Gokul P. Srinivasaragavan, Hamid Hamidani, Genevieve Schroeder +28
We present optical, radio, and X-ray observations of EP250108a/SN 2025kg, a broad-line Type Ic supernova (SN Ic-BL) accompanying an Einstein Probe (EP) fast X-ray transient (FXT) a…
Multi-Wavelength Analysis of AT 2023sva: a Luminous Orphan Afterglow With Evidence for a Structured Jet
Gokul P. Srinivasaragavan, Daniel A. Perley, Anna Y. Q. Ho +50
We present multi-wavelength analysis of ZTF23abelseb (AT 2023sva), an optically discovered fast-fading ( mag in days), luminous ( mag) and…
Evidence for a strong 19.5 Hz flux oscillation in Swift BAT and Fermi GBM gamma-ray data from GRB 211211A
Cecilia Chirenti, Simone Dichiara, Amy Lien +1
The gamma-ray burst (GRB) GRB~211211A is believed to have occurred due to the merger of two neutron stars or a neutron star and a black hole, despite its duration of more than a mi…
Characterizing the Ordinary Broad-lined Type Ic SN 2023pel from the Energetic GRB 230812B
Gokul P. Srinivasaragavan, Vishwajeet Swain, Brendan M. O'Connor +39
We report observations of the optical counterpart of the long gamma-ray burst (LGRB) GRB 230812B, and its associated supernova (SN) SN 2023pel. The proximity () and high…
The Uncertain Future of Massive Binaries Obscures the Origin of LIGO/Virgo Sources
K. Belczynski, A. Romagnolo, A. Olejak +6
The LIGO/Virgo gravitational--wave observatories have detected 50 BH-BH coalescences. This sample is large enough to have allowed several recent studies to draw conclusions about t…
NICER X-ray Observations of Seven Nearby Rotation-Powered Millisecond Pulsars
S. Guillot, M. Kerr, P. S. Ray +18
NICER observed several rotation-powered millisecond pulsars to search for or confirm the presence of X-ray pulsations. When broad and sine-like, these pulsations may indicate therm…
A Search for High-Energy Counterparts to Fast Radio Bursts
Virginia Cunningham, S. Bradley Cenko, Eric Burns +8
We report on a search for high-energy counterparts to fast radio bursts (FRBs) with the Fermi Gamma-ray Burst Monitor (GBM), Fermi Large Area Telescope (LAT), and the Neil Gehrels…
Gravitational waves from f-modes excited by the inspiral of highly eccentric neutron star binaries
Cecilia Chirenti, Roman Gold, M. Coleman Miller
As gravitational wave instrumentation becomes more sensitive, it is interesting to speculate about subtle effects that could be analyzed using upcoming generations of detectors. On…
PSR J0007+7303 in the CTA1 SNR: New Gamma-ray Results from Two Years of Fermi-LAT Observations
A. A. Abdo, K. S. Wood, M. E. DeCesar +8
One of the main results of the Fermi Gamma-Ray Space Telescope is the discovery of γ-ray selected pulsars. The high magnetic field pulsar, PSR J0007+7303 in CTA1, was the first eve…
Implications of the PSR 1257+12 Planetary System for Isolated Millisecond Pulsars
M. Coleman Miller, Douglas P. Hamilton
The first extrasolar planets were discovered in 1992 around the millisecond pulsar PSR 1257+12. We show that recent developments in the study of accretion onto magnetized stars, pl…
