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…

A Phenomenological Study of the Accretion Disk in the Super-Eddington AGN I Zw 1

Farin Drewes, Roberta Vieliute, Juan V. Hernández Santisteban +11

The structure of the accretion disk in AGN is still an unsolved question, especially how it may change with Eddington ratio. Here we examine the accretion disk in the super-Eddingt…

Continuum Reverberation Mapping of Accretion Disks Surrounding Supermassive Black Hole Binaries: Observational Signatures

Yi-Xin Fu, Yan-Rong Li, Jian-Min Wang +9

It has remained challenging to reliably identify sub-parsec supermassive black hole binaries (SMBHBs), despite them being expected to be ubiquitous. We propose a new method using m…

PyTICS: An Iterative Method for Photometric Lightcurve Intercalibration using Comparison Stars

Roberta Vieliute, Juan V. Hernández Santisteban, Keith Horne +1

Intensive reverberation mapping monitoring programs combine ground-based photometric observations from different telescopes, requiring intercalibration of lightcurves to reduce sys…

EDGE: The direct link between mass growth history and the extended stellar haloes of the faintest dwarf galaxies

Alex Goater, Justin I. Read, Noelia E. D. Noël +9

Ultra-faint dwarf galaxies (UFDs) are commonly found in close proximity to the Milky Way and other massive spiral galaxies. As such, their projected stellar ellipticity and extende…
