Spatially Resolved Spectroscopy of Starburst and Post-Starburst Galaxies in The Rich z~0.55 Cluster CL0016+16

, 2010
We have used the Low Resolution Imaging Spectrograph (LRIS) on the W.M. Keck I telescope to obtain spatially resolved spectroscopy of a small sample of six post-starburst and three dusty-starburst galaxies in the rich cluster CL0016+16 at z=0.55.

Anomalous Microwave Emission from Star Forming Regions

Advances in Astronomy, Volume 2013, Issue 1, 2013., 2013
The evidence for microwave emission from spinning dust grains has been strengthened considerably by its detection in a number of discrete astrophysical objects associated with star formation. These detections, in combination with statistical constraints on its presence on large angular scales in the diffuse ISM, have provided strong observational ...

AGN/Starburst Connection

Acta Polytechnica CTU Proceedings, 2014
Two main physical processes characterize the activity in the nuclear region of active galaxies: an intense star formation (starburst, SB) and an Active Galactic Nucleus (AGN).

Post-starburst galaxies: more than just an interesting curiosity

, 2009
From the VIMOS VLT DEEP Survey (VVDS) we select a sample of 16 galaxies with spectra which identify them as having recently undergone a strong starburst and subsequent fast quenching of star formation.

DISCOVERY OF LARGE MOLECULAR GAS RESERVOIRS IN POST-STARBURST GALAXIES [PDF]

, 2015
Post-starburst (or “E+A”) galaxies are characterized by low Hα emission and strong Balmer absorption, suggesting a recent starburst, but little current star formation.

Overtone Transition 2ν1 of HCO+ and HOC+: Origin, Radiative Lifetime, Collisional Quenching

ChemPhysChem, Volume 25, Issue 21, November 4, 2024.
The C−H/O−H stretch vibration overtone of one of the simplest molecular ion isomeric systems HCO+/HOC+ is studied in a cryogenic ion trap experiment. Moreover, our comprehensive “zero background” method enables the determination of radiative lifetimes and select quenching reaction rates at the same time.

Properties of the Hii Regions Derived Using Integral Field Spectroscopy

Advances in Astronomy, Volume 2013, Issue 1, 2013., 2013
Here we review some of our more recent results on the observed properties of Hii regions using Integral Field Spectroscopy. In particular, we illustrate the use of this technique to study in detail the ionization conditions across the nebulae for galactic Hii regions (focused on the Orion Nebula) and the statistical study of large samples of ...

What triggers galaxy transformations? The environments of post-starburst galaxies [PDF]

, 2006
(abridged) There are good observational reasons to believe that the progenitors of red galaxies have undergone starbursts, followed by a post-starburst phase.

A POPULATION OF INTERMEDIATE-MASS BLACK HOLES IN DWARF STARBURST GALAXIES UP TO REDSHIFT = 1.5 [PDF]

, 2015
We study a sample of ∼50,000 dwarf starburst and late-type galaxies drawn from the COSMOS survey with the aim of investigating the presence of nuclear accreting black holes (BHs) as those seed BHs from which supermassive BHs could grow in the early ...
