Exploring Detection Statistics for Microlensing Events

Alaina Schweitzer, R. A. Street, K. Kruszyńska, A. Udalski et autres

Abstract In this research we aim to develop a baseline filter for microlensing events in the timeseries photometry from the BlackGEM imaging survey using a variety of statistical parameters. Our project has focused on exploring the viability of different statistical parameters for …

Discovery of a radio-flaring M dwarf in a commensal transient search of the LADUMA field

Moses Mlangeni, P. A. Woudt, Paul J Groot, Alex Andersson et autres

ABSTRACT We report the discovery and characterization of MKT J032848.4–271904.6, a new radio transient identified in the LADUMA field using SARAO Science Data Processor SDP UHF-band images from approximately 1 yr of MeerKAT observations. Using the Transient Pipeline TraP and advanced filtering …

Proto-NUX: A Prototype Telescope for Ground-based Near-ultraviolet Observations

Rasjied Sloot, Rudy Wijnands, S. Bloemen, Rik ter Horst et autres

Abstract The Near-UV-eXplorer (NUX) is a proposed ground-based, wide-field telescope array with a field of view of ∼70 square degrees, designed to operate over the 300–350 nm wavelength range and to achieve a target sensitivity of 20 mag in 150 s (5 …

A catalog to unite them all: REGALADE, a revised galaxy compilation for the advanced detector era

Hugo Tranin, N. Blagorodnova, M. A. Gómez-Muñoz, Maxime Wavasseur et autres

Context . Many applications in transient science, gravitational wave follow-up, and galaxy population studies require all-sky galaxy catalogs with reliable distances, extents, and stellar masses. However, existing catalogs often lack completeness beyond ~100 Mpc, suffer from stellar contamination, or do not provide …

Textual interpretation of transient image classifications from large language models

Fiorenzo Stoppa, Turan Bulmus, S. Bloemen, S. J. Smartt et autres

Modern astronomical surveys deliver immense volumes of transient detections, yet distinguishing real astrophysical signals (for example, explosive events) from bogus imaging artefacts remains a challenge. Convolutional neural networks are effectively used for real versus bogus classification; however, their reliance on opaque latent …

The most distant optically polarised GRB afterglow: GRB 240419A at z = 5.178

R. Brivio, S. Covino, M. Ferro, A. Saccardi et autres

Context. Gamma-ray bursts (GRBs) are extremely bright phenomena powered by relativistic jets arising from explosive events at cosmological distances. The nature of the jet and the configuration of the local magnetic fields are still unclear, with the distinction between different models possibly …

Many applications in transient science, gravitational wave follow-up, and galaxy population studies require all-sky galaxy catalogs with reliable distances, extents, and stellar masses. However, existing catalogs often lack completeness beyond $\sim 100$ Mpc, suffer from stellar contamination, or do not provide homogeneous …

EP 250108a/SN 2025kg: Observations of the Most Nearby Broad-line Type Ic Supernova Following an Einstein Probe Fast X-Ray Transient

Jillian Rastinejad, A. J. Levan, P. G. Jonker, C. D. Kilpatrick et autres

Abstract With a small sample of fast X-ray transients (FXTs) with multiwavelength counterparts discovered to date, their progenitors and connections to γ-ray bursts (GRBs) and supernovae (SNe) remain ambiguous. Here, we present photometric and spectroscopic observations of SN 2025kg, the SN counterpart …
