The Effect of Galaxy Interactions on Molecular Gas Properties [PDF]
Astrophysical Journal, 2018 Galaxy interactions are often accompanied by an enhanced star formation rate (SFR). Since molecular gas is essential for star formation, it is vital to establish whether and by how much galaxy interactions affect the molecular gas properties.

The changing GMC population in galaxy interactions [PDF]
Monthly notices of the Royal Astronomical Society, 2018 With the advent of modern observational efforts providing extensive giant molecular cloud catalogues, understanding the evolution of such clouds in a galactic context is of prime importance.

Galaxy Interactions Trigger Rapid Black Hole Growth: an unprecedented view from the Hyper Suprime-Cam Survey [PDF]
, 2017 Collisions and interactions between gas-rich galaxies are thought to be pivotal stages in their formation and evolution, causing the rapid production of new stars, and possibly serving as a mechanism for fueling supermassive black holes (BH).

Catching Tidal Dwarf Galaxies at a Later Evolutionary Stage with ALFALFA
The Astronomical Journal, 2023 We present deep optical imaging and photometry of four objects classified as “Almost-Dark” galaxies in the Arecibo Legacy Fast Arecibo L-band Feed Array (ALFALFA) survey because of their gas-rich nature and extremely faint or missing optical emission in ...

Star formation triggered by galaxy interactions in modified gravity [PDF]
, 2016 Together with interstellar turbulence, gravitation is one key player in star formation. It acts both at galactic scales in the assembly of gas into dense clouds, and inside those structures for their collapse and the formation of pre-stellar cores.

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.

THE SAMI GALAXY SURVEY: GALAXY INTERACTIONS AND KINEMATIC ANOMALIES IN ABELL 119 [PDF]
, 2016 Galaxy mergers are important events that can determine the fate of a galaxy by changing its morphology, star formation activity and mass growth. Merger systems have commonly been identified from their disturbed morphologies, and we now can employ ...

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 ...

A Multiwavelength Study of Active Galactic Nuclei in Post-merger Remnants
The Astrophysical Journal, 2023 We investigate the role of galaxy mergers in triggering active galactic nuclei (AGN) in the nearby universe. Our analysis is based on a sample of 79 post-merger remnant galaxies with deep X-ray observations from Chandra/XMM-Newton capable of detecting a ...
