Anomaly detection in Fink. I. Discovery, follow-up, and classification of unusual sources
M. V. Pruzhinskaya, M. V. Kornilov, A. V. Dodin +19
Modern wide-field time-domain surveys produce alert streams whose scientific potential is often concentrated in rare and unusual events. Efficient discovery therefore requires auto…
The eruptive young star IRAS 21204+4913
M. A. Burlak, A. V. Dodin, A. V. Zharova +7
The results of photometric, polarimetric, and spectroscopic observations are presented for the young star IRAS 21204+4913, whose visible brightness has increased by $\approx 5^{\rm…
The jet and circumstellar environment of the young binary DF Tau
A. V. Dodin, M. A. Burlak, V. A. Kiryukhina +5
Jets and disc winds play an important role in the evolution of protoplanetary discs and the formation of planetary systems. However, there is still a lack of observational data reg…
EP240801a/XRF 240801B: An X-ray Flash Detected by the Einstein Probe and Implications of its Multiband Afterglow
Shuai-Qing Jiang, Dong Xu, Agnes P. C. van Hoof +89
We present multiband observations and analysis of EP240801a, a low-energy, extremely soft gamma-ray burst (GRB) discovered on August 1, 2024 by the Einstein Probe (EP) satellite, w…
Transient narrow high-velocity absorptions in the stationary spectra of SS433
A. V. Dodin, K. A. Postnov, A. M. Cherepashchuk +1
We report on the discovery of rare emergence (31 nights from 360 nights of observations) of narrow absorption features in hydrogen and helium lines in stationary SS433 spectra with…
The BVRcIc sky brightness of the Caucasian Mountain Observatory of MSU
I. A. Komarova, A. M. Tatarnikov, A. V. Sharonova +4
In this paper we analyse the measurements of the brightness of the night sky above the CMO SAI MSU in the visible and near-infrared range made in 2019-2014. In 2023-2024 the median…
