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,...

First Byurakan survey plate scan service

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...

The First Byurakan Survey (FBS) is the largest and the first systematic objective prism survey of the extragalactic sky. It covers 17,000 sq.deg. in the Northern sky together...

description: VOEvent alerts produced from transient detections resulting from observations with the NASA Fermi Large Area Telescope. Events should be reported within tens to of...

This table contains basic metadata as well as the spectra from the Digital First Byurakan Survey (DFBS).

Quenching of star formation plays a fundamental role in galaxy evolution. This process occurs due to the removal of the cold interstellar medium (ISM) or stabilization against...

We present observations of the blazar 3C 279 at 22GHz using the space VLBI mission RadioAstron on 2018 January 15. Images in both total intensity and fractional polarization are...

We examine the connection between galaxy mergers and the triggering of active galactic nuclei (AGNs) using a sample of 614 type 1 AGNs at z<0.07, along with a control sample...

UV and optical continuum reverberation mapping is a powerful tool for probing the accretion disk and inner broad-line region. However, recent reverberation mapping campaigns in...

Most active galactic nuclei (AGN) are believed to be surrounded by a dusty molecular torus on the parsec scale, which is often embedded within a larger circumnuclear disk (CND)....

We present the results of our ALMA<~0.5kpc resolution dense molecular line (HCN and HCO^+^J=2-1, J=3-2, and J=4-3) observations of 12 nearby (ultra)luminous infrared galaxies...

Gamma-ray flares of blazars may be accompanied by high-energy neutrinos due to interactions of high-energy cosmic rays in the jet with photons, as suggested by the detection of...

Narrow-line Seyfert 1 (NLS1) galaxies are a type of active galactic nuclei (AGN) that were originally classified as sources with little to no radio emission. Although the class...

Accreting supermassive black holes at the centres of galaxies are the engine of active galactic nuclei (AGN). X-ray light curves of unabsorbed AGN show dramatic random...

We present maps of the ionized gas flux distributions, excitation, star formation rate (SFR), surface mass density {Sigma}H+, and obtain total values of SFR and ionized gas...

We characterize for the first time the torus properties of an ultra-hard X-ray (14-195keV) volume-limited (D_L_<40Mpc) sample of 24 Seyfert (Sy) galaxies (BCS_40_ sample)....

The global influence of AGN-driven outflows remains uncertain, due to a lack of large samples with accurately-determined outflow properties. In the second paper of this series,...

We present 1-7GHz high-resolution radio imaging (VLA and e-MERLIN) and spatially resolved ionized gas kinematics for 10 z<0.2 type 2 'obscured' quasars...

In the SSA22 field which exhibits a large-scale proto-cluster at z=3.1, we carried out a spectroscopic survey for Lyman Break Galaxies (LBGs) with the VLT/VIMOS and identified...
