The ePESSTO+ census of ZTF nuclear transients. I. What flares in galactic nuclei?

E. Concepción, T. Petrushevska, G. Leloudas +21

Transients in galactic nuclei arise from distinct processes, only some of which trace the supermassive black hole (SMBH). These include tidal disruption events (TDEs), changing-loo…

AT2025agpz in Rubin commissioning data: distinguishing a luminous interacting supernova from nuclear transients in compact galaxies

C. R. Angus, M. Quilt, H. F. Stevance +37

The Vera C. Rubin Observatory's Legacy Survey of Space and Time will discover unprecedented numbers of rare, long-lived optical transients, many of which will be too faint or too n…

Old Universe, Young SNe Ia: A Statistical Analysis of Type Ia Supernova Progenitor Age from 6,983 TITAN Host Galaxies, and Implications for Cosmology

Yukei Murakami, Jack Tweddle, Phil Wiseman +17

Correlations between standardized Type Ia supernova (SN Ia) luminosities and host-galaxy properties are routinely modeled to avoid bias in cosmological parameter inference. A recen…

An Extremely Luminous Flare Recorded from a Supermassive Black Hole

Matthew J. Graham, Barry McKernan, K. E. Saavik Ford +17

Since their discovery more than 60 years ago, accreting supermassive black holes in active galactic nuclei (AGN) were recognized as highly variable sources, requiring an extremely…

Infrared observations reveal the reprocessing envelope in the tidal disruption event AT 2019azh

Thomas M. Reynolds, Lars Thomsen, Seppo Mattila +14

Tidal disruption events (TDEs) are expected to release much of their energy in the far-ultraviolet (UV), which we do not observe directly. However, infrared (IR) observations can o…

First joint absorption and T-based metallicity measured in a GRB host galaxy at using JWST/NIRSpec

Anne Inkenhaag, Patricia Schady, Phil Wiseman +20

We present the first gamma-ray burst (GRB) host galaxy with a measured absorption line and electron temperature (T) based metallicity, using the temperature sensitive [OIII]…

First IFU observations of two GRB host galaxies at cosmic noon with JWST/NIRSpec

B. Topçu, P. Schady, S. Wuyts +16

Long gamma-ray bursts (GRBs) serve as powerful probes of distant galaxies. Their luminous afterglow pinpoints galaxies independent of luminosity, in contrast to most flux-limited s…

A systematically-selected sample of luminous, long-duration, ambiguous nuclear transients

P. Wiseman, R. D. Williams, I. Arcavi +12

We present a search for luminous, long-duration ambiguous nuclear transients (ANTs) similar to the unprecedented discovery of the extreme, ambiguous event AT2021lwx with a \,…

Comparing emission- and absorption-based gas-phase metallicities in GRB host galaxies at using JWST

P. Schady, R. M. Yates, L. Christensen +34

Much of what is known of the chemical composition of the universe is based on emission line spectra from star forming galaxies. Emission-based inferences are, nevertheless, model-d…
