Multiwavelength Study of Young Massive Star Clusters in the Interacting Galaxy Arp 24 [PDF]

, 2006
We made a multiwavelength study of young massive star clusters (YSCs) in the interacting galaxy Arp 24 using optical and ultraviolet images from the Hubble Space Telescope (HST), the Sloan Digital Sky Survey, and the Galaxy Evolution Explorer, mid ...

A Physically Motivated Framework to Compare Pair Fractions of Isolated Low- and High-mass Galaxies across Cosmic Time

The Astrophysical Journal
Low-mass galaxy pair fractions are understudied, and it is unclear whether low-mass pair fractions evolve in the same way as more massive systems over cosmic time. In the era of JWST, Roman, and Rubin, selecting galaxy pairs in a self-consistent way will

Chandra Observations of the Interacting NGC 4410 Galaxy Group

, 2003
We present high resolution X-ray imaging data from the ACIS-S instrument on the Chandra telescope of the nearby interacting galaxy group NGC 4410. Four galaxies in the inner portion of this group are clearly detected by Chandra, including the peculiar ...

Atomic Hydrogen and Star Formation in the Bridge/Ring Interacting Galaxy Pair NGC 7714/7715 (Arp 284) [PDF]

, 1997
We present high spatial resolution 21 cm H I maps of the interacting galaxy pair NGC 7714/7715. We detect a massive (2 × 109 M☉) H I bridge connecting the galaxies that is parallel to but offset from the stellar bridge. A chain of H II regions traces the

Astronomical Image Superresolution Reconstruction with Deep Learning for Better Identification of Interacting Galaxies

The Astrophysical Journal Supplement Series
Galaxy–galaxy mergers are crucial in galaxy evolution, but the tidal features around galaxies are often faint, making it difficult to identify interacting or merging galaxies.

The Signatures of Self-interacting Dark Matter and Subhalo Disruption on Cluster Substructure

The Astrophysical Journal, 2022
The abundance, distribution, and inner structure of satellites of galaxy clusters can be sensitive probes of the properties of dark matter. We run 30 cosmological zoom-in simulations with self-interacting dark matter (SIDM), with a velocity-dependent ...

3C459: A highly asymmetric radio galaxy with a starburst

, 2003
Multifrequency radio observations of the radio galaxy 3C459 using MERLIN, VLA and the EVN, and an optical HST image using the F702W filter are presented.

Evolution of Galaxies Through Their Interactions [PDF]

Symposium - International Astronomical Union, 1996
We investigated how the encounters between galaxies change their mass M and velocity dispersion σ. We carried out a series of direct N-body simulation of encounters of two spherical galaxies. In Figure 1, the relative change of energy ΔE/E are plotted against that of mass ΔM/M for various initial conditions.

A study of galaxy interactions

, 2014
This work describes the in-depth study of two systems of interacting galaxies, namely Arp 10 and VII Zw466. Both systems belong to a special group of interacting galaxies known as collisional ring and ring-like galaxies. A typical ring galaxy emerges when a companion galaxy passes through or near the center of a larger rotating disk galaxy driving ring-
