  • Magellan sp. obs. of galaxies with z~0.95 in UDS

    While galaxy clusters are dominated by quiescent galaxies in the local Universe, they show a wide range in quiescent galaxy fraction (QF) at higher redshifts. Here we present...
  • Massive star-forming galaxies from JWST and ALMA

    We present an analysis of the JWST NIRCam and MIRI morphological and structural properties of 80 massive (log10(M*[M_{sun_)])=11.2+/-0.1) dusty star-forming galaxies at...
  • ZTF DR1 light curves of SNe Type Ia

    Type Ia supernovae (SNe Ia) in the nearby Hubble flow are excellent distance indicators in cosmology. The Zwicky Transient Facility (ZTF) has observed a large sample of SNe from...
  • Radio and {Gamma}-ray of MOJAVE-Fermi AGNs

    Within the MOJAVE VLBA programme (Monitoring of Jets in AGN with VLBA Experiments), we have accumulated observational data at 15 GHz for hundreds of jets in gamma-ray bright...
  • Blazars study with ZTF DR6 and Roma-BZCAT

    We investigate the temporal and colour variability of 897 blazars, comprising 455 BL Lacertae objects (BL Lacs) and 442 Flat Spectrum Radio Quasars (FSRQs), selected from the...
  • Galaxy LF with GAMA and KiDS data

    In this study, we present a new experimental design using clustering-based redshift inference to measure the evolving galaxy luminosity function (GLF) spanning 5.5 decades from...
  • Galaxies with redshifts in the vicinity of A426

    We study the global kinematics of the Perseus galaxy cluster (A426) at redshift z=0.017 using a large sample of galaxies from our new MMT/Hectospec spectroscopic observation for...
  • Ellipticals and brightest cluster galaxies param.

    We investigate the roles of major and minor mergers during brightest cluster galaxy (BCG) assembly using surface brightness profiles, line indices, and fundamental plane...
  • Ccold molecular gas depletion in AGN hosts

    The energy released by active galactic nuclei (AGN) has the potential to heat or remove the gas of the ISM, thus likely impacting the cold molecular gas reservoir of host...
  • Changing-look AGN. I. Main sequence transition

    This paper is the first in a series of papers that prepare and analyze spectral and other properties for a database of already-discovered changing-look active galactic nuclei...
  • BH masses for AGNs behind the MCs from MQS & OGLE

    We use the spectroscopic data collected by the Magellanic Quasars Survey (MQS) and the photometric V- and I-band data from the Optical Gravitational Lensing Experiment (OGLE) to...
  • Deep uGMRT 250-850MHz view of Coma cluster galaxies

    We present high-resolution, high-sensitivity upgraded Giant Metrewave Radio Telescope observations of the Coma cluster (A1656) at 250-500MHz and 550-850MHz. At 250-500MHz, 135...
  • Extreme emission-line galaxies at z~4-9

    Extreme emission line galaxies (EELGs) are typically characterized by high equivalent widths (EWs) which are driven by elevated specific star formation rates (sSFR) in low-mass...
  • Recent star formation galaxies sample

    On the basis of the Galaxy Evolution Explore (GALEX) ultraviolet (UV) data, many studies have demonstrated that recent star formation (RSF) is common in early-type galaxies. In...
  • Ly{alpha} absorbers redshifts

    We present redshift-space two-point ({xi}), three-point ({dzeta}), and reduced three- point (Q) correlation of Ly{alpha} absorbers (Voigt profile components having HI column...
  • High-redshift quasars spectra

    Despite the increasing prevalence of radio-loud (RL) sources at cosmic noon, our understanding of the underlying physics that governs the accretion disc outflows in these...
  • The Pantheon+ analysis: cosmological constraints

    We present constraints on cosmological parameters from the Pantheon+ analysis of 1701 light curves of 1550 distinct Type Ia supernovae (SNeIa) ranging in redshift from z=0.001...
  • Merger-AGN connection in the NW-2 field

    Galaxy mergers represent a fundamental physical process under hierarchical structure formation, but their role in triggering active galactic nuclei (AGNs) is still unclear. We...
  • JADES NIRCam & NIRSpec phot. & line fluxes cat. (DR1-DR3)

    JWST has revolutionized the field of extragalactic astronomy with its sensitive and high-resolution infrared view of the distant Universe. Adding to the new legacy of JWST...
  • Ex-situ stellar mass fractions for MaNGA

    The hierarchical model of galaxy evolution suggests that the impact of mergers is substantial on the intricate processes that drive stellar assembly within a galaxy. However,...
