Warm Molecular Gas in Galaxy-Galaxy Merger NGC 6090 [PDF]

The Astrophysical Journal, 2004
We present observations of the CO 2-1 and 3-2 transitions toward the merging galaxies of NGC6090 with the Submillimeter Array (SMA) (The Submillimeter Array (SMA) is a joint project between the Smithsonian Astrophysical Observatory and the Academia Sinica Institute of Astronomy and Astrophysics, and is funded by the Smithsonian Institution and the ...

Merger driven explosive evolution of distant galaxies (minor mergers) [PDF]

Astrophysical Bulletin, 2013
We derived solutions for the Smoluchowski kinetic equation for the mass function of galaxies, which describes mergers in differential approximation, where mergers with low-mass galaxies are the dominant factor. The evolution of the initial distribution is analyzed as well as the influence of the source represented by galaxies (halos) that separate from

Mergers and galaxy assembly [PDF]

The 9th astrophysics conference: After the dark ages, when galaxies were young (the Universe at 2<Z<5), 1999
Theoretical considerations and observational data support the idea that mergers were more frequent in the past. At redshifts z = 2 to 5, violent interactions and mergers may be implicated by observations of Lyman-break galaxies, sub-mm starbursts, and active galactic nuclei.

Automatic quantitative morphological analysis of interacting galaxies [PDF]

, 2013
The large number of galaxies imaged by digital sky surveys reinforces the need for computational methods for analyzing galaxy morphology. While the morphology of most galaxies can be associated with a stage on the Hubble sequence, morphology of galaxy ...

Targeted decrease of portal hepatic pressure gradient improves ascites control after TIPS

Hepatology, EarlyView., 2022
The river diagram demonstrates that after transjugular intrahepatic portosystemic shunt insertion (TIPS) the majority of patients without ascites and 50% of the patients with ascites detectable at ultrasound, show the best response in the long term follow‐up.

The Effect of Gas Fraction on the Morphology and Time-scales of Disc Galaxy Mergers [PDF]

, 2009
Gas-rich galaxy mergers are more easily identified by their disturbed morphologies than mergers with less gas. Because the typical gas fraction of galaxy mergers is expected to increase with redshift, the under-counting of low gas-fraction mergers may ...

The Merger Rate of Massive Galaxies [PDF]

The Astrophysical Journal, 2006
We calculate the projected two point correlation function for samples of luminous and massive galaxies in the COMBO-17 photometric redshift survey, focusing particularly on the amplitude of the correlation function at small projected radii and exploring the constraints such measurements can place on the galaxy merger rate.

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 ...

The Chandra view of galaxy mergers [PDF]

Monthly Notices of the Royal Astronomical Society, 2007
From a Chandra survey of nine interacting galaxy systems the evolution of X-ray emission during the merger process has been investigated. It is found that the X-ray luminosity peaks ~300 Myr before nuclear coalescence, and then dips, even though we know that rapid and increasing activity is still taking place at this time.
