Gaussian model fit components for 3C345
The flat-spectrum radio quasar 3C 345 has been showing gamma-ray activity since the mid-2000s along with activity across the electromagnetic spectrum. A gamma-ray burst in 2009... -
Archive of AGN spectral observations
The archive of AGN spectral observations is obtained on AZT-8 telescope at the Fesenkov Astrophysical Institute (FAI), Almaty, Kazakhstan. It represents the result of... -
MeerKAT Absorption Line Survey (MALS). I. DR1
The MeerKAT Absorption Line Survey (MALS) has observed 391 telescope pointings at the L band (900-1670MHz) at {delta}<~+20{deg}. We present radio continuum images and a... -
Xray obs. of gal. hosting nuclear star clusters
We analyze Chandra X-ray Observatory imaging of 108 galaxies hosting nuclear star clusters (NSCs) to search for signatures of massive black holes (BHs). NSCs are extremely dense... -
MALS SALT-NOT survey of MIR-selected AGN at z<3.5
We present results of an optical spectroscopic survey using SALT and the Nordic Optical Telescope to build a Wide-field Infrared Survey Explorer mid-infrared color-based,... -
Seyfert 1 AGNs with X-ray sp. from NuSTAR+Swift
The corona is an integral component of active galactic nuclei (AGNs) which produces the bulk of the X-ray emission above 1-2keV. However, many of its physical properties and the... -
Optical classification of BZG objects
In the blazar catalog BZCAT the objects are divided into 4 types: BZB, BZQ, BZG, and BZU. In this paper BZG objects are studied in order to determine their physical nature. Of... -

Sasmirala Subarcsecond mid-infrared atlas of local AGN
These FITS images were generated with the IDL package MIRphot [Asmus2014] by extraction (and combination) of the sub-images from the chopped/nodded total images from COMICS,... -
Sasmirala Subarcsecond mid-infrared atlas of local AGN, Cone Search
The Subarcsecond mid-infrared (MIR) atlas of local active galactic nuclei (AGN) is a collection of all available N- and Q-band images obtained at ground-based 8-meter class... -
