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.

Mapping the dynamics, star-formation rates, and chemical properties of galaxies with integral field spectroscopy [PDF]

, 2005
Major advances in the development of instruments for eight and ten meter class telescopes are revolutionising our understanding of galaxy formation. In particular, Integral Field Spectrographs (which produce a three dimensional {x, y, velocity) map of a ...

Star formation and molecular gas properties of post-starburst galaxies [PDF]

, 2023
Post-starburst galaxies are believed to be in a rapid transition between major merger starbursts and quiescent ellipticals. Their optical spectrum is dominated by A-type stars, suggesting a starburst that was quenched recently. While optical observations

Sparks: The Magellan/FIRE Survey from Starburst to Post-starburst

The Astrophysical Journal
Rapid transitions from starburst to quiescence constitute a key evolutionary pathway in galaxy formation. Post-starburst galaxies trace this brief phase, exhibiting optical spectra dominated by intermediate-age stellar populations with strong Balmer ...

A polarimetry study of starburst galaxies [PDF]

, 1996
Optical imaging polarimetry has been carried out for a number of starburst galaxies under various morphological classifications. In several cases, kpc-scale reflection nebulae are detected which arise from dust grains scattering starburst radiation ...

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.

The impact of cosmic filaments on starburst galaxies across cosmic times

Astronomy & Astrophysics
Cosmological simulations suggest that various galaxy properties depend on their location within the cosmic web. Yet direct observational evidence of the dependence of star formation activity on distance to filaments remains scarce and is missing at z ≳ 1.

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 ...
