Finite-Horizon Robustness Analysis under Mixed Disturbances using Signal-IQCs

Frederik Thiele, Harald Pfifer, Felix Biertümpfel

Common worst-case analyses for uncertain finite-horizon systems consider quadratic performance metrics based on the strict Bounded Real Lemma. Thus, they assess system performance…

Multi-band optical photometric variability of the blazar OJ 287 from 2015 to 2025

Alok C. Gupta, Karan Dogra, Mark Kidger +101

We present the most densely sampled multi-band optical photometric observations of the peculiar BL Lacertae object OJ 287 from 2015 to 2025 with a focus on its optical activity on…

GOTO065054+593624: a 8.5 mag amplitude dwarf nova identified in real time via Kilonova Seekers

T. L. Killestein, G. Ramsay, M. Kennedy +62

Dwarf novae are astrophysical laboratories for probing the nature of accretion, binary mass transfer, and binary evolution -- yet their diverse observational characteristics contin…

Host galaxy magnitude of OJ 287 from its colours at minimum light

Mauri J. Valtonen, Lankeswar Dey, S. Zola +54

OJ 287 is a BL Lacertae type quasar in which the active galactic nucleus (AGN) outshines the host galaxy by an order of magnitude. The only exception to this may be at minimum ligh…

Constraining the Evolution of Cataclysmic Variables via the Masses and Accretion Rates of their Underlying White Dwarfs

A. F. Pala, B. T. Gänsicke, D. Belloni +28

We report on the masses (), effective temperatures () and secular mean accretion rates () of 43 cataclysmic variable (CV) wh…

Evidence for mass accretion driven by spiral shocks onto the white dwarf in SDSS J123813.73-033933.0

A. F. Pala, B. T. Gänsicke, T. R. Marsh +21

We present high-time-resolution photometry and phase-resolved spectroscopy of the short-period () cataclysmic variable SDSS J123813.73-033933.…
