Caught in the act: Interaction-driven evolution in the nearby compact galaxy group Robert's Quartet (SCG0018-4854)

S. Keshri, Sudhanshu Barway, Mousumi Das, Abhishek Paswan

We present a spatially resolved multiwavelength study of the compact galaxy group Robert's Quartet (RQ; SCG0018-4854), aimed at understanding interaction-driven galaxy evolution in dense environments. The system comprises four galaxies (NGC 87, NGC 88, NGC 89, and NGC 92) that span a …

Age bimodality in pseudo-bulges of barred spiral galaxies: bar-driven evolution across cosmic time

Kavin Kumar N R, S. Keshri, Sudhanshu Barway

ABSTRACT We investigate the stellar population properties of pseudo-bulges in barred galaxies drawn from the Sloan Digital Sky Survey Data Release 7 to assess how bars regulate central star formation and secular evolution. Our sample comprises barred spiral and barred lenticular (S0) …

Kinematics of the lens host S0 galaxy NGC 1553: Role of secular processes

S. Keshri, Sudhanshu Barway, F. Combes

We investigated the central structure of the S0 galaxy NGC 1553, to understand its origin and the underlying dynamical processes that shape it. The high-resolution integral field spectroscopic data from the Multi Unit Spectroscopic Explorer (MUSE) reveal a well-ordered rotation pattern, consisting …

Unveiling the kinematics of a central region in the triple-AGN host NGC 7733-7734 interacting group

S. Keshri, Sudhanshu Barway, Mousumi Das, Jyoti Yadav et autres

We present a detailed study of the interacting triple active galactic nuclear system, NGC 7733-34, focusing on stellar kinematics, ionised gas characteristics, and star formation within the central region and stellar bars of both galaxies. We performed a comprehensive analysis using archival …

Measurement of double-parton scattering in inclusive production of four jets with low transverse momentum in proton-proton collisions at $$ \sqrt{s} $$ = 13 TeV

A. Tumasyan, W. Adam, J. W. Andrejkovic, T. Bergauer et autres

Abstract A measurement of inclusive four-jet production in proton-proton collisions at a center-of-mass energy of 13 TeV is presented. The transverse momenta of jets within |η| < 4.7 are required to exceed 35, 30, 25, and 20 GeV for the first-, second-, …
