Dark matter phenomenology of high-speed galaxy cluster collisions

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
We perform a general computational analysis of possible post-collision mass distributions in high-speed galaxy cluster collisions in the presence of self-interacting dark matter.

The Mismeasure of Mergers: Revised Limits on Self-interacting Dark Matter in Merging Galaxy Clusters [PDF]

open access: yesAstrophysical Journal, 2017
In an influential recent paper, Harvey et al. derive an upper limit to the self-interaction cross section of dark matter (DM) ( σ DM / m < 0.47 cm2 g−1 at 95% confidence) by averaging the DM–galaxy offsets in a sample of merging galaxy clusters.

Modelling ISO Galaxy Counts with Luminosity and Merger Rate Evolution [PDF]

open access: yes, 1998
We model galaxy evolution in the 6.75 and 15 micron passbands of the ISO satellite, by combining models of galaxy evolution at optical wavelengths (which are consistent with the optical galaxy counts) with observed spectral energy distributions in the ...

UNCOVERING THE DEEPLY EMBEDDED ACTIVE GALACTIC NUCLEUS ACTIVITY IN THE NUCLEAR REGIONS OF THE INTERACTING GALAXY Arp 299 [PDF]

open access: yes, 2013
We present mid-infrared (MIR) 8–13 μm spectroscopy of the nuclear regions of the interacting galaxy Arp 299 (IC 694+NGC 3690) obtained with CanariCam (CC) on the 10.4 m Gran Telescopio Canarias (GTC).

Janus kinase 2 inhibition by pacritinib as potential therapeutic target for liver fibrosis

open access: yesHepatology, 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 ...

AN INTERACTING GALAXY SYSTEM ALONG A FILAMENT IN A VOID [PDF]

open access: yes, 2013
Cosmological voids provide a unique environment for the study of galaxy formation and evolution. The galaxy population in their interiors has properties significantly different from average field galaxies. As part of our Void Galaxy Survey (VGS), we have

The Role of AGN in Luminous Infrared Galaxies from the Multiwavelength Perspective

open access: yesUniverse, 2022
Galaxy mergers provide a mechanism for galaxies to effectively funnel gas and materials toward their nuclei and fuel the central starbursts and accretion of supermassive black holes.

Galaxy Interactions: The Hi Signature [PDF]

open access: yesSymposium - 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.
