SDSS-IV MaNGA: How Galaxy Interactions Influence Active Galactic Nuclei
The Astrophysical Journal, 2023 We present a comparative study of active galactic nuclei (AGN) between galaxy pairs and isolated galaxies with the final data release of the MaNGA integral field spectroscopic survey.

The Astrophysical Journal, 2023 Pairs of galaxies hosting active galactic nuclei (AGNs) are powerful probes of merger-driven supermassive black hole (SMBH) growth as they can resolve individual AGNs and trace mergers over a large range of physical separations.

The Effect of Age on the Grouping of Open Clusters: II—Are There Old Binary Clusters?
Universe, 2022 In the present study, we continue testing the Primordial Group hypothesis (Casado 2022), which postulates that only sufficiently young open clusters can be binary or multiple, and old clusters are essentially single.

Detection of the Low-stellar-mass Host Galaxy of a z ∼ 6.25 Quasar with JWST
The Astrophysical Journal, 2023 We characterize the stellar mass of J2239+0207, a z ∼ 6.25 sub-Eddington quasar ( M _1450 = −24.6), using dedicated JWST/NIRCam medium-band observations of a nearby point-spread function star to remove the central point source and reveal the underlying ...

NO THE HOLMBERG EFFECT FOR GALAXY PAIRS SELECTED FROM THE SDSS DR9 AT Z ≤ 0:06
Odessa Astronomical Publications, 2016 We studied the Holmberg effect in galaxy pairs selected from the SDSS DR9, where 60561galaxies were limited by redshift 0.02 < z < 0.06 and absolute magnitude: Mr ≤ −20.7 m for central galaxies (N=18578) and Mr > −21.5 m for neighbor galaxies (N=41983 ...

Sunyaev Zel’dovich high resolution view of filamentary structures between galaxy clusters pairs [PDF]
EPJ Web of Conferences, 2022 Strong observational and theoretical evidences suggest that about half of the baryons in the Universe should lie outside galaxy clusters in a lowdensity and hot phase in filaments connecting galaxy clusters.

The Astrophysical Journal, 2023 The recent discovery of enormous Ly α nebulae (ELANe), characterized by physical extents >200 kpc and Ly α luminosities >10 ^44 erg s ^−1 , provides a unique opportunity to study the intergalactic medium and circumgalactic medium in distant galaxies ...

The Study of the Circumgalactic Medium with Quasar Pairs
The Astrophysical Journal Supplement Series, 2023 We have collected 10,025 foreground–background quasar pairs with projected distances d _p < 500 kpc from the large quasar catalog of the Sloan Digital Sky Survey DR16Q. We investigate the properties of the Mg ii absorption lines with W _r > 0.15 Å around

Statistics of Galactic-scale Quasar Pairs at Cosmic Noon
The Astrophysical Journal, 2023 The statistics of galactic-scale quasar pairs can elucidate our understanding of the dynamical evolution of supermassive black hole (SMBH) pairs, the duty cycles of quasar activity in mergers, or even the nature of dark matter, but they have been ...
