H. E. S. S. Collaboration, :, H. Abdalla +265
Aims: Following the detection of the fast radio burst FRB150418 by the SUPERB project at the Parkes radio telescope, we aim to search for very-high energy gamma-ray afterglow emiss…
Wait for it: Post-supernova winds driven by delayed radioactive decays
Ken J. Shen, Josiah Schwab
In most astrophysical situations, the radioactive decay of 56Ni to 56Co occurs via electron capture with a fixed half-life of 6.1 days. However, this decay rate is significantly sl…
A search for spectral hysteresis and energy-dependent time lags from X-ray and TeV gamma-ray observations of Mrk 421
A. U. Abeysekara, S. Archambault, A. Archer +220
Blazars are variable emitters across all wavelengths over a wide range of timescales, from months down to minutes. It is therefore essential to observe blazars simultaneously at di…
A Search for Kilonovae in the Dark Energy Survey
Z. Doctor, R. Kessler, H. Y. Chen +68
The coalescence of a binary neutron star (BNS) pair is expected to produce gravitational waves (GW) and electromagnetic (EM) radiation, both of which may be detectable with current…
New physical insights about Tidal Disruption Events from a comprehensive observational inventory at X-ray wavelengths
Katie Auchettl, James Guillochon, Enrico Ramirez-Ruiz
We perform a comprehensive study of the X-ray emission from 70 transient sources which have been classified as a tidal disruption event (TDE) in the literature. We explore the prop…
Deeper H.E.S.S. observations of Vela Junior (RX J0852.04622): Morphology studies and resolved spectroscopy
H. E. S. S. Collaboration, H. Abdalla, A. Abramowski +260
Aims. We study gamma-ray emission from the shell-type supernova remnant (SNR) RX J0852.04622 to better characterize its spectral properties and its distribution over the SNR. Me…
Ultraluminous X-ray bursts in two ultracompact companions to nearby elliptical galaxies
Jimmy A. Irwin, W. Peter Maksym, Gregory R. Sivakoff +8
An X-ray flaring source was found near the galaxy NGC 4697. Two flares were seen, separated by four years. The flux increased by a factor of 90 on a timescale of about one minute.…
Characterizing the gamma-ray long-term variability of PKS 2155-304 with H.E.S.S. and Fermi-LAT
H. E. S. S. Collaboration, H. Abdalla, A. Abramowski +244
Studying the temporal variability of BL Lac objects at the highest energies provides unique insights into the extreme physical processes occurring in relativistic jets and in the v…
Formation of Tidal Captures and Gravitational Wave Inspirals in Binary-Single Interactions
Johan Samsing, Morgan MacLeod, Enrico Ramirez-Ruiz
We perform the first systematic study on how dynamical stellar tides and general relativistic (GR) effects affect the dynamics and outcomes of binary-single interactions. For this,…
The Properties of Short gamma-ray burst Jets Triggered by neutron star mergers
Ariadna Murguia-Berthier, Enrico Ramirez-Ruiz, Gabriela Montes +6
The most popular model for short gamma-ray bursts (sGRBs) involves the coalescence of binary neutron stars. Because the progenitor is actually hidden from view, we must consider un…
A Stringent Limit on the Mass Production Rate of -Process Elements in the Milky Way
Phillip Macias, Enrico Ramirez-Ruiz
We analyze data from several studies of metal-poor stars in the Milky Way, focusing on both strong (Eu) and weak (Sr) -process elements. Because these elements were injected in…
A Search for Very High-Energy Gamma Rays from the Missing Link Binary Pulsar J1023+0038 with VERITAS
E. Aliu, S. Archambault, A. Archer +82
The binary millisecond radio pulsar PSR J1023+0038 exhibits many characteristics similar to the gamma-ray binary system PSR B1259--63/LS 2883, making it an ideal candidate for the…
