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.

COSMOS-Web: The Role of Galaxy Interactions and Disk Instabilities in Producing Starbursts at z < 4

The Astrophysical Journal
We study of the role of galaxy–galaxy interactions and disk instabilities in producing starburst activity in galaxies out to z = 4. For this, we use a sample of 387 galaxies with robust total star formation rate measurements from Herschel, gas masses ...

Wolf–Rayet stars in starburst galaxies [PDF]

New Astronomy Reviews, 2000
Wolf-Rayet stars have been detected in a large number of galaxies experiencing intense bursts of star formation. All stars initially more massive than a certain, metallicity-dependent, value are believed to experience the Wolf-Rayet phase at the end of their evolution, just before collapsing in supernova explosion.

THE RADIO–GAMMA CORRELATION IN STARBURST GALAXIES [PDF]

, 2015
We present a systematic study of non-thermal electron–proton plasma and its emission processes in starburst galaxies in order to explain the correlation between the luminosity in the radio band and the recently observed gamma luminosity.

Post-starburst quasars: bridging the gap between post-starburst galaxies and quasars [PDF]

, 2015
In order to better understand the nature of post-starburst quasars (PSQs) in the context of galaxy evolution, we compare their properties to those of post-starburst galaxies and quasars from appropriately selected samples possessing similar redshift ($z \

The Mitchell Spectrograph: Studying Nearby Galaxies with the VIRUS Prototype

Advances in Astronomy, Volume 2013, Issue 1, 2013., 2013
The Mitchell Spectrograph (a.k.a. VIRUS‐P) on the 2.7 m Harlan J. Smith telescope at McDonald Observatory is currently the largest field of view (FOV) integral field unit (IFU) spectrograph in the world (1.7′ × 1.7′). It was designed as a prototype for the highly replicable VIRUS spectrograph which consists of a mosaic of IFUs spread over a 16 ...

The Nature of Starburst Galaxies

The Astrophysical Journal, 1996
Utilizing a large sample of infrared-selected starburst galaxies having optical images and long-slit spectra, we explore the interrelationships between the properties of starbursts and relate these properties to those of the "host" galaxy. We find that the half-light radius of the Hα-emitting region (re, Hα) enters into several correlations that ...

HCO⁺in the Starburst Galaxy M82 [PDF]

The Astrophysical Journal, 1998
We report observations and an analysis of the distribution of HCO+(1-0) and HCO+(4-3) emission in the central 1 kpc star forming region of M82. Comparisons are made with other star formation indicators such as the mm continuum, the distribution of radio SNR's and the molecules CO and OH. In a broad sense, the HCO+ is distributed in a way similar to the

HIGH-J CO VERSUS FAR-INFRARED RELATIONS IN NORMAL AND STARBURST GALAXIES [PDF]

, 2015
We present correlations between 9 CO transitions ( J = 4 – 3 ?> to 12 – 11 ?> ) and beam-matched far-infrared (far-IR) luminosities ( L FIR , b ?> ) among 167 local galaxies, using Herschel Spectral and Photometric Imaging Receiver Fourier Transform ...
