Dual and lensed AGN at sub-arcsecond separations uncovered by ERIS
M. V. Zanchettin, F. Mannucci, Q. D'Amato +62
We present the first results of the ongoing INAF GTO program focused on the search of sub-arcsecond dual AGN, carried out with the near-infrared integral-field unit SPIFFIER of the…
Cosmic Duets II. Growth and accretion in Gaia Multi-Peak dual AGN at Cosmic Noon
M. Scialpi, F. Mannucci, D. Izquierdo-Villalba +36
We present the first statistical characterization of the physical properties of Cosmic Duets: dual AGN in the redshift range 0.5 z 3.0 with projected separations of 1…
Finding the evolutionary link between ULIRGs and radio galaxies
Ayisha Fida, Sumana Nandi, Mousumi Das +4
Ultraluminous infrared galaxies (ULIRGs) are the remnants of the major mergers of gas-rich galaxies. They are dusty systems and are extremely luminous in the infrared. Both starbur…
Radio Galaxies and Jet Duty Cycles
M. J. Hardcastle, C. Konar, S. Dutta +10
Radio-luminous active galactic nuclei, or radio galaxies, are the brightest population of objects in the extragalactic radio sky and will be seen in large numbers in essentially ev…
SKAVLBI view of AGN jets in the early Universe
C. Spingola, M. Mezcua, Y. Liu +33
Active Galactic Nuclei (AGN) are among the brightest sources in the Universe, and those that are also jetted are uniquely valuable at the earliest epochs, because their relativisti…
Evolution of AGN Across Cosmic Epochs with the SKAO
R. Kondapally, V. Singh, G. Mazzolari +10
Understanding the evolution of active galactic nuclei (AGN) and their host galaxies across cosmic epochs is one of the key science drivers of extragalactic astronomy. The detection…
Euclid: Quick Data Release (Q1)- The connection between galaxy close encounters and radio activity
M. Magliocchetti, A. La Marca, L. Bisigello +165
Using the large statistics provided by both Euclid and the LOFAR surveys, we present the first large-scale study of the connection between radio emission, its morphology, and the m…
Jet-mode feedback in NGC 5972: insights from resolved MUSE, GMRT and VLA observations
Arshi Ali, Biny Sebastian, Darshan Kakkad +10
NGC 5972, a Voorwerp galaxy, features a helical-shaped extended emission-line region (EELR) with a radius > 10 kpc and a S-shaped radio structure spanning about 470 kpc. We use VLT…
An Accreting Supermassive Black Hole Buried in a Faint Dwarf Galaxy
Abhishek Paswan, Mousumi Das, K Rubinur
In the last decade, there have been several discoveries of Active Galactic Nuclei (AGN) in dwarf galaxies including an AGN in an ultra-compact dwarf galaxy with a Black Hole mass $…
A VLBA-uGMRT search for candidate binary black holes: Study of six X-shaped radio galaxies with double-peaked emission lines
Biny Sebastian, Anderson Caproni, Preeti Kharb +6
Identifying methods to discover dual AGN has proven to be challenging. Several indirect tracers have been explored in the literature, including X/S-shaped radio morphologies and do…
Study of Star-formation in Dual Nuclei Galaxies using UVIT observations
K. Rubinur, M. Das, P. Kharb +3
We have used the Ultraviolet Imaging Telescope (UVIT) aboard AstroSat to study star formation in a sample of nine dual nuclei galaxies with separations ~11 kpc, which is an expecte…
AGN Feedback Through Multiple Jet Cycles in the Seyfert Galaxy NGC 2639
Vaishnav V. Rao, Preeti Kharb, Rubinur K. +7
The Seyfert galaxy NGC 2639 was known to exhibit three episodes of AGN jet/lobe activity. We present here the upgraded Giant Metrewave Radio Telescope (uGMRT) 735 MHz image of NGC…
Dynamical Modelling and Emission Signatures of a Candidate Dual AGN with Precessing Radio Jets
Gourab Giri, Ravi Pratap Dubey, K. Rubinur +2
In this paper, we have modelled the dynamical and emission properties (in the presence of radiative losses and diffusive shock acceleration) of an observed S-shaped radio source (2…
A Multi-wavelength Study of the Dual Nuclei in Mrk 212
K. Rubinur, P. Kharb, M. Das +5
We present radio observations of the galaxy merger remnant Mrk 212 with the Karl G. Jansky Very Large Array (VLA) and the upgraded Giant Meter Radio Telescope (uGMRT). Mrk 212 has…
The Intriguing Parsec-Scale Radio Structure in the "Offset AGN" KISSR 102
P. Kharb, D. Lena, Z. Paragi +4
We report the detection of an intriguing parsec-scale radio source in the "offset AGN" candidate, KISSR 102. The elliptical host galaxy includes two optical nuclei at a projected s…
Understanding Galaxy Mergers & AGN Feedback with UVIT
K. Rubinur, M. Das, P. Kharb +1
Simulations expect an enhanced star-formation and active galactic nuclei (AGN) activity during galaxy mergers, which can lead to formation of binary/dual AGN. AGN feedback can enha…
Searching for Dual AGN in Galaxies with Double-Peaked Emission Line Spectra using Radio Observations
K. Rubinur, M. Das, P. Kharb
Supermassive black hole (SMBH) binaries form due to galaxy mergers and minor accretion events. When the SMBHs are accreting, they form dual or binary AGN and can give rise to doubl…
Searching for Dual Active Galactic Nuclei
Rubinur Khatun, M. Das, P. Kharb
Binary or dual active galactic nuclei (DAGN) are expected from galaxy formation theories. However, confirmed DAGN are rare and finding these systems has proved to be challenging. R…
