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…

Time-Domain Photometry and Activity Evolution of Interstellar Comet 3I/ATLAS with BHTOM

A. Fraser Gillan, Łukasz Wyrzykowski, Przemysław J. Mikołajczyk +69

Time-domain photometric monitoring is essential for characterizing cometary evolution, particularly for rare interstellar objects with limited observing opportunities. We aimed to…

Gaia20fnr: A binary-lens microlensing event with full orbital motion revealed by four space telescopes

M. Wicker, Ł. Wyrzykowski, M. Hundertmark +49

The microlensing event Gaia20fnr is a long-duration, non-caustic-crossing binary-lens event at high Galactic latitude. Triggered by a photometric rise detected by the Gaia space mi…

A search for transit timing variations in the transiting hot Jupiter systems HIP 65, NGTS-6, NGTS-10 and WASP-173

A. W. Griffiths, J. Southworth, L. Alegre +30

Hot Jupiters are Jupiter-mass planets with orbital periods of less than ten days. Their short orbital separations make tidal dissipation within the stellar host especially efficien…
