Estimators of Bolometric Luminosity and Black Hole Mass with Mid-infrared Continuum Luminosities for Dust-obscured Quasars: Prevalence of Dust-obscured SDSS Quasars

Dohyeong Kim, Myungshin Im, Minjin Kim +4

We present bolometric luminosity () and black hole (BH) mass () estimators based on mid-infrared (MIR) continuum luminosity (hereafter, ) that…

A lanthanide-rich kilonova in the aftermath of a long gamma-ray burst

Yu-Han Yang, Eleonora Troja, Brendan O'Connor +24

Observationally, Kilonovae are astrophysical transients powered by the radioactive decay of nuclei heavier than iron, synthesized in the merger of two compact objects. Over the fir…

The Early Light Curve of a Type Ia Supernova 2021hpr in NGC 3147: Progenitor Constraints with the Companion Interaction Model

Gu Lim, Myungshin Im, Gregory S. H. Paek +19

The progenitor system of Type Ia supernovae (SNe Ia) is expected to be a close binary system of a carbon/oxygen white dwarf (WD) and a non-degenerate star or another WD. Here, we p…

Unusual Hard X-ray Flares Caught in NICER Monitoring of the Binary Supermassive Black Hole Candidate AT2019cuk/Tick Tock/SDSS J1430+2303

Megan Masterson, Erin Kara, Dheeraj R. Pasham +17

The nuclear transient AT2019cuk/Tick Tock/SDSS J1430+2303 has been suggested to harbor a supermassive black hole (SMBH) binary near coalescence. We report results from high-cadence…

Spectral evolution of dark asteroid surfaces induced by space weathering over a decade

Sunao Hasegawa, Francesca E. DeMeo, Michael Marsset +20

The surface of airless bodies like asteroids in the Solar System are known to be affected by space weathering. Experiments simulating space weathering are essential for studying th…
