Rotating Starburst Cores in Massive Galaxies at z = 2.5 [PDF]

, 2017
We present spatially resolved ALMA observations of the CO emission line in two massive galaxies at z = 2.5 on the star-forming main sequence. Both galaxies have compact dusty star-forming cores with effective radii of and in the 870 μm continuum emission.

CO-Observations of Post-Starburst Galaxies

Astrophysics and Space Science, 2001
The so-called starburst phenomenon is an issue of great importance for the evolution of galaxies. Although a lot of progress has been made in this field, it is still unknown how they evolve.

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 ...

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.

Chemical Evolution of the Universe and its Consequences for Gravitational‐Wave Astrophysics

Annalen der Physik, Volume 536, Issue 2, February 2024.
Population properties of double compact object mergers (especially binary black holes) are sensitive to the metallicity dependent cosmic star formation history. The uncertainty of this quantity cannot be ignored and makes the interpretation of current gravitational wave observations difficult.

The Study of Nebular Emission on Nearby Spiral Galaxies in the IFU Era

Advances in Astronomy, Volume 2013, Issue 1, 2013., 2013
A new generation of wide‐field emission‐line surveys based on integral field units (IFU) is allowing us to obtain spatially resolved information of the gas‐phase emission in nearby late‐type galaxies, based on large samples of HII regions and full two‐dimensional coverage.

Cool Gas in the Circumgalactic Medium of Massive Post Starburst Galaxies

The Open Journal of Astrophysics
Observing the interplay between galaxies and their gaseous surroundings is crucial for understanding how galaxies form and evolve, including the roles of long-lived cool gas reservoirs, starburst and AGN driven outflows.
