The First Photometric Evidence of a Transient/Variable Source at z > 5 with JWST

The Astrophysical Journal
The James Webb Space Telescope (JWST) discovered 79 transients out to z ∼ 4.8 through the JADES Transient Survey (JTS), but the JTS did not find any z > 5 transients.

Eight Years of Light from ASASSN-15oi: Toward Understanding the Late-time Evolution of TDEs

The Astrophysical Journal
We present results from an extensive follow-up campaign of the tidal disruption event (TDE) ASASSN-15oi spanning δt  ∼ 10–3000 days, offering an unprecedented window into the multiwavelength properties of a TDE during its first ≈8 yr of evolution. ASASSN-

The Effect of the Velocity Distribution on Kilonova Emission

The Astrophysical Journal
The electromagnetic emission from the nonrelativistic ejecta launched in neutron star mergers (either dynamically or through a disk wind) has the potential to probe both the total mass and composition of this ejecta.

The Radio Counterpart to the Fast X-Ray Transient EP240414a

The Astrophysical Journal
Despite being operational for only a short time, the Einstein Probe mission, with its large field of view and rapid localization capabilities, has already significantly advanced the study of rapid variability in the soft X-ray sky.

The Nature of Optical Afterglows without Gamma-Ray Bursts: Identification of AT2023lcr and Multiwavelength Modeling

The Astrophysical Journal
In the past few years, the improved sensitivity and cadence of wide-field optical surveys have enabled the discovery of several afterglows without associated detected gamma-ray bursts (GRBs).

Delayed X-Ray Brightening Accompanied by Variable Ionized Absorption Following a Tidal Disruption Event

The Astrophysical Journal
Supermassive black holes can experience super-Eddington peak mass fallback rates following the tidal disruption of a star. The theoretical expectation is that part of the infalling material is expelled by means of an accretion disk wind, whose ...
