First Multimessenger Observations of a Neutron Star Merger

Raffaella Margutti, Ryan Chornock

We describe the first observations of the same celestial object with gravitational waves and light. * GW170817 was the first detection of a neutron star merger with gravitational w…

Urca Nuclide Production in Type-I X-ray Bursts and Implications for Nuclear Physics Studies

Grant Merz, Zach Meisel

The thermal structure of accreting neutron stars is affected by the presence of urca nuclei in the neutron star crust. Nuclear isobars harboring urca nuclides can be produced in th…

Combining Electromagnetic and Gravitational-Wave Constraints on Neutron-Star Masses and Radii

Mohammad Al-Mamun, Andrew W. Steiner, Joonas Nättilä +6

We perform a joint Bayesian inference of neutron-star mass and radius constraints based on GW170817, observations of quiescent low-mass X-ray binaries (QLMXBs), photospheric radius…

Discovery of the optical afterglow and host galaxy of short GRB181123B at : Implications for Delay Time Distributions

K. Paterson, W. Fong, A. Nugent +19

We present the discovery of the optical afterglow and host galaxy of the {\it Swift} short-duration gamma-ray burst, GRB\,181123B. Observations with Gemini-North starting at $\appr…

The distant, galaxy cluster environment of the short GRB 161104A at and a comparison to the short GRB host population

Anya E. Nugent, Wen-fai Fong, Yuxin Dong +9

We present optical observations of the Swift short-duration gamma-ray burst (GRB) GRB 161104A and its host galaxy at . We model the multiband photometry and spec…

GW190814 as a massive rapidly-rotating neutron star with exotic degrees of freedom

V. Dexheimer, R. O. Gomes, T. Klähn +2

In the context of the massive secondary object recently observed in the compact-star merger GW190814, we investigate the possibility of producing massive neutron stars from a few d…

On the minimum radius of very massive neutron stars

Sophia Han, Madappa Prakash

Prospects of establishing the radii of massive neutron stars in PSR J1614-2230 and PSR J0740+6620 from NICER and Chandra observatories hold the potential to constrain the equation…

Sensitivity of Ti and Ni production in CCSN shock-driven nucleosynthesis to reaction rates

Shiv K. Subedi, Zach Meisel, Grant Merz

Recent observational advances have enabled high resolution mapping of Ti in core-collapse supernova (CCSN) remnants. Comparisons between observations and models provide st…

NS 1987A in SN 1987A

Dany Page, Mikhail V. Beznogov, Iván Garibay +3

The possible detection of a compact object in the remnant of SN 1987A presents an unprecedented opportunity to follow its early evolution. The suspected detection stems from an exc…

An extremely energetic supernova from a very massive star in a dense medium

Matt Nicholl, Peter K. Blanchard, Edo Berger +14

The interaction of a supernova with a circumstellar medium (CSM) can dramatically increase the emitted luminosity by converting kinetic energy to thermal energy. In 'superluminous'…

The Tidal Disruption Event AT 2018hyz II: Light Curve Modeling of a Partially Disrupted Star

Sebastian Gomez, Matt Nicholl, Philip Short +18

AT 2018hyz (=ASASSN-18zj) is a tidal disruption event (TDE) located in the nucleus of a quiescent E+A galaxy at a redshift of , first detected by the All-Sky Automated…
