A broadband outburst of the compact steep-spectrum quasar 3C 138 in 2024-2026
T. V. Mufakharov, Yu. V. Sotnikova, V. V. Vlasyuk +20
After several decades of relative quiescence, the compact steep-spectrum quasar 3C 138 entered an active phase in 2024-2026, exhibiting strong broadband flaring. We investigate its…
Multiwavelength quasi-periodic variability of the blazar Ton 599
Yu. V. Sotnikova, T. V. Mufakharov, A. E. Volvach +34
During the last 40-50 years, the TeV blazar Ton 599 has systematically experienced major outbursts detected in a wide wavelength range from radio to -rays. In this work, we pres…
A satellite orbit drift in binary near-Earth asteroids (66391) 1999 KW4 and (88710) 2001 SL9 -- Indication of the BYORP effect
P. Scheirich, P. Pravec, P. Kušnirák +34
We obtained thorough photometric observations of two binary near-Earth asteroids (66391) Moshup = 1999 KW4 and (88710) 2001 SL9 taken from 2000 to 2019 and derived physical and dyn…
A search for HeH+ and CH in a high-redshift QSO
I. Zinchenko, V. Dubrovich, C. Henkel
We performed a search for the HeH+ J=1-0 line (ν_{rest} = 2010.183873 GHz) and simultaneously for the CH ^2Π_{3/2}(F_2)J=3/2 - ^2Π_{1/2}(F_2)J=1/2 lines (ν_{rest}\approx 2006.8 and…
