Isolated Galaxies versus Interacting Pairs with MaNGA
Galaxies, 2015 We present preliminary results of the spectral analysis on the radial distributions of the star formation history in both a galaxy merger and a spiral isolated galaxy observed with MaNGA.

On the characteristics of tidal structures of interacting galaxies [PDF]
, 2011 We present the results of our analysis of the geometrical tidal tail characteristics for nearby and distant interacting galaxies. The sample includes more than two hundred nearby galaxies and about seven hundred distant ones.

Tidal Dwarf Galaxies: Disc Formation at \(z\simeq0\)
Galaxies, 2015 Collisional debris around interacting and post-interacting galaxies often display condensations of gas and young stars that can potentially form gravitationally bound objects: Tidal Dwarf Galaxies (TDGs).

Harnessing the Hubble Space Telescope Archives: A Catalog of 21,926 Interacting Galaxies
The Astrophysical Journal, 2023 Mergers play a complex role in galaxy formation and evolution. Continuing to improve our understanding of these systems requires ever larger samples, which can be difficult (even impossible) to select from individual surveys.

Galaxy Zoo: quantifying morphological indicators of galaxy interaction★ [PDF]
Monthly Notices of the Royal Astronomical Society, 2012 We use Galaxy Zoo 2 visual classifications to study the morphological signatures of interaction between similar-mass galaxy pairs in the Sloan Digital Sky Survey. We find that many observable features correlate with projected pair separation; not only obvious indicators of merging, disturbance and tidal tails, but also more regular features, such as ...

Self-interacting dark matter on small and large scales
SciPost Physics Proceedings, 2023 In the self-interacting dark matter paradigm (hereafter SIDM), dark matter (DM) is assumed to have non-gravitational interactions with itself. SIDM has been constrained by observations of galaxy clusters. More recently, measurements of large DM densities

Galaxy Interactions: The Hi Signature [PDF]
Symposium - International Astronomical Union, 1999 HI observations are an excellent tool for investigating tidal interactions. Ongoing major and minor interactions which can lead to traumatic mergers or to accretion and the triggering of star formation, show distinct HI signatures. Interactions and mergers in the recent past can also be recognized in the HI structure and kinematics.

Mid-Infrared Evidence for Accelerated Evolution in Compact Group Galaxies [PDF]
, 2009 We find evidence for accelerated evolution in compact group galaxies from the distribution in mid-infrared colorspace of 42 galaxies from 12 Hickson Compact Groups (HCGs) compared to the the distributions of several other samples including the LVL+SINGS ...

Janus kinase 2 inhibition by pacritinib as potential therapeutic target for liver fibrosis
Hepatology, EarlyView., 2022 Diagram of the activation of the profibrotic and procontractile Janus kinase 2 (JAK2)/Ras homolog family member A/Rho‐kinase pathway and the inhibition of phosphorylated JAK2 by pacritinib to inhibit hepatic stellate cell activity. Abstract Background and Aims Janus kinase 2 (JAK2) signaling is increased in human and experimental liver fibrosis with ...

Interactions, Starbursts, and Star Formation
Galaxies, 2015 We study how interactions between galaxies affect star formation within them by considering a sample of almost 1500 of the nearest galaxies, all within a distance of ∼45 Mpc. We use the far-IR emission to define the massive star formation rate (SFR), and
