KINEMATICS OF STELLAR POPULATIONS IN POSTSTARBURST GALAXIES [PDF]
The Astrophysical Journal, 2015 Post-starburst galaxies host a population of early-type stars (A or F), but simultaneously lack indicators of ongoing star formation such as OII emission. Two distinct stellar populations have been identified in these systems: a young post-starburst population superimposed on an older host population.

THE SINS SURVEY OF z ∼ 2 GALAXY KINEMATICS: PROPERTIES OF THE GIANT STAR-FORMING CLUMPS [PDF]
, 2010 We have studied the properties of giant star-forming clumps in five z ∼ 2 star-forming disks with deep SINFONI AO spectroscopy at the ESO VLT. The clumps reside in disk regions where the Toomre Q-parameter is below unity, consistent with their being ...

A group of merging galaxies falling into Abell 2142
Astronomy & AstrophysicsGalaxy clusters produce a very hostile environment for galaxies: their gas gets stripped by ram pressure, they undergo galaxy interactions, and their star formation is quenched.

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology
Deep Underground Science and Engineering, EarlyView.This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Kinematic Profiles of SO Galaxies
The Astronomical Journal, 1997 Stellar rotation curves, velocity dispersion profiles, and line-of-sight velocity distributions (LOSVD) as derived from absorption lines are presented for the major axes of 18 S0 and two elliptical galaxies. Ionized gas rotation curves and dispersions were measured from the [O III] 5007 Angstrom emission line in the 9 S0 galaxies displaying this ...
