Detection of quasi-periodic oscillations in the 37 GHz radio light curve of the blazar Ton 599 during 1990-2020
Alok C. Gupta, Alexandr E. Volvach, Shubham Kishore +6
Blazars are a subclass of radio-loud active galactic nuclei (AGNs) that display strong multi-wavelength variability on diverse timescales ranging from years down to minutes. In the…
GRB 201015A: from seconds to months of optical monitoring and supernova discovery
S. Belkin, A. S. Pozanenko, P. Y. Minaev +21
We present full photometric coverage and spectroscopic data for soft GRB 201015A with a redshift z = 0.426. Our data spans a time range of 85 days following the detection of GRB. T…
Multi-wavelength temporal variability of the blazar PKS 1510-089
Q. Yuan, Pankaj Kushwaha, Alok C. Gupta +13
We perform correlation and periodicity search analyses on long-term multi-band light curves of the FSRQ 1510-089 observed by the space-based Fermi--Large Area Telescope in gamma-ra…
A Keplerian disk with a four-arm spiral birthing an episodically accreting high-mass protostar
R. A. Burns, Y. Uno, N. Sakai +34
High-mass protostars (M 8 M) are thought to gain the majority of their mass via short, intense bursts of growth. This episodic accretion is thought to be faci…
Powerful flare phenomena in water vapor maser lines in the emerging protostellar system with protoplanetary disks IRAS 16293-2422
A. E. Volvach, L. N. Volvach, M. G. Larionov
Based on the long-term monitoring data of the water maser since 2019.0 to 2021.0 allowed us detecting in IRAS 16293-2422 two powerful phenomena lasted about year at radial velociti…
Infrared observations of the flaring maser source G358.93-0.03 -- SOFIA confirms an accretion burst from a massive young stellar object
B. Stecklum, V. Wolf, H. Linz +24
Class II methanol masers are signs of massive young stellar objects (MYSOs). Recent findings show that MYSO accretion bursts cause flares of these masers. Thus, maser monitoring ca…
