The SEDs of interacting galaxies [PDF]
Proceedings of the International Astronomical Union, 2011 AbstractThe evolution of galaxies is greatly influenced by their interactions. As part of a program to study interacting galaxies, we have measured and modeled the spectral energy distributions (SEDs) from the ultraviolet (UV) to the far-infrared (FIR).

GRB 190114C in the nuclear region of an interacting galaxy [PDF]
Astronomy & Astrophysics, 2019 Context. For the first time, very high energy emission up to the TeV range has been reported for a gamma-ray burst (GRB). It is still unclear whether the environmental properties of GRB 190114C might have contributed to the production of these very high ...

INTERACTIONS OF GALAXIES IN THE GALAXY CLUSTER ENVIRONMENT [PDF]
The Astrophysical Journal, 2009 We study the dependence of galaxy properties on the clustercentric radius and the environment attributed to the nearest neighbor galaxy using the SDSS galaxies associated with the Abell galaxy clusters. We find that there exists a characteristic scale where the properties of galaxies suddenly start to depend on the clustercentric radius at fixed ...

Submillimeter Array Observations of Extended CO (J = 2 − 1) Emission in the Interacting Galaxy NGC 3627 [PDF]
Astrophysical Journal, 2018 We present moderate (∼5″) and high angular resolution (∼1″) observations of 12CO (J = 2 − 1) emission toward the nearby interacting galaxy NGC 3627 taken with the Submillimeter Array (SMA).

Optical spectroscopy of young tidal objects around two interacting galaxy pairs [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We present Gemini Multi-Object Spectrograph (GMOS) spectra of HI-rich tidal features located around the outskirts of two interacting galaxy pairs, NGC 3166/9 and NGC 4725/47.

Dark matter mass loss in galaxy flybys: dependence on impact parameter [PDF]
Serbian Astronomical Journal, 2022 Galaxy flybys, interactions where two independent halos inter-penetrate but detach at a later time and do not merge, occur frequently at lower redshifts.

Formation of a Massive Lenticular Galaxy Under the Tidal Interaction with a Group of Dwarf Galaxies
The Astrophysical Journal Letters, 2023 Based on the atomic-hydrogen (H i ) observations using the Five-hundred-meter Aperture Spherical radio Telescope, we present a detailed study of the gas-rich massive S0 galaxy NGC 1023 in a nearby galaxy group.

Analysis of candidates for interacting galaxy clusters. I. A1204 and A2029-A2033 [PDF]
, 2018 Merging galaxy clusters allows to study the different mass components, dark and baryonic, separately. Also their occurrence enables to test the $\Lambda$CDM scenario and they could put constrains in the self interacting cross section of the dark matter ...

Active galactic nuclei and galaxy interactions [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 We perform a statistical analysis of AGN host characteristics and nuclear activity for AGNs in pairs and without companions. Our study concerns a sample of AGNs derived from the SDSS-DR4 data by Kauffmann et al (2003) and pair galaxies obtained from the same data set by Alonso et al. (2006).

Simulations of the star-forming molecular gas in an interacting M51-like galaxy [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We present here the first of a series of papers aimed at better understanding the evolution and properties of giant molecular clouds (GMCs) in a galactic context.
