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…
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…
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…
Discovery of a pseudobulge galaxy launching powerful relativistic jets
J. K. Kotilainen, J. Leon Tavares, A. Olguin-Iglesias +4
Supermassive black holes launching plasma jets at close to speed of light, producing gamma-rays, have ubiquitously been found to be hosted by massive elliptical galaxies. Since ell…
The host galaxies of active galactic nuclei with powerful relativistic jets
A. Olguín-Iglesias, J. León-Tavares, J. K. Kotilainen +6
We present deep Near-infrared (NIR) images of a sample of 19 intermediate-redshift () radio-loud active galactic nuclei (AGN) with powerful relativistic jets ($L_{1.4GHz…
