Infrared Dark Clouds and high-mass star formation activity in Galactic Molecular Clouds
R. Retes-Romero, Y. D. Mayya, A. Luna +1
Ever since their discovery, Infrared dark clouds (IRDCs) are generally considered to be the sites just at the onset of high-mass (HM) star formation. In recent years, it has been r…
Flare-like Variability of the Mg~II 2798 Å Emission Line and UV Fe~II band in the Blazar CTA~102
Vahram Chavushyan, Víctor M. Patiño-Álvarez, Raúl A. Amaya-Almazán +1
We report on the detection of a statistically significant flare-like event in the Mg~II~ 2798~Å emission line and the UV~Fe~II band of CTA~102 during the outburst of autumn 2017…
Long-term optical spectral monitoring of a changing-look AGN NGC 3516 I: Continuum and broad-line flux variability
A. I. Shapovalova, L. C. Popovic, V. L. Afanasiev +11
Here we present the long-term optical spectral monitoring of a changing-look active galactic nuclei (AGN) NGC 3516 that covers 22 years (from 1996 to 2018). We explore a variabilit…
Characterization and Performance of the Cananea Near-infrared Camera (CANICA)
R. Devaraj, Y. D. Mayya, L. Carrasco +1
We present details of characterization and imaging performance of the Cananea Near-infrared camera (CANICA) at the 2.1m telescope of the Guillermo Haro Astrophysical Observatory (O…
The star formation law in Galactic high-mass star-forming molecular clouds
R. Retes-Romero, Y. D. Mayya, A. Luna +1
We study the star formation (SF) law in 12 Galactic molecular clouds with ongoing high-mass star formation (HMSF) activity, as traced by the presence of a bright IRAS source and ot…
Long-term optical spectral monitoring of NGC 7469
Alla I. Shapovalova, L. C. Popović, V. H. Chavushyan +11
We present the results of the long-term (20-year period, from 1996 to 2015) optical spectral monitoring of the Seyfert 1 galaxy NGC 7469. The variation in the light-curves of the b…
