An automated polarimeter and its use in the study of active galaxies [PDF]

, 1996
In this thesis I present the design and development of an automated polarimeter for use in mapping the percentage levels and position angles of linearly polarized light from extended astronomical objects.

Starburst galaxies

, 2006
Star formation and the Starburst phenomenon are presented with respect to a number of nearby star-forming galaxies where our understanding of the process can be calibrated.

SQuIGG E: Buried Star Formation Cannot Explain the Rapidly Fading CO(2–1) Luminosity in Massive, z ∼ 0.7 Post-starburst Galaxies

The Astronomical Journal
Observational and theoretical studies have long held that rapid gas consumption in starbursts is responsible for the formation of the most massive quiescent galaxies at high redshift.

Unveiling the evolutionary history of local post-starburst galaxies through careful Bayesian modelling of their spectra

When we gaze upon the night sky into the stars in the Milky Way, it seems that the cosmos is constant, at least in the timescale of a lifetime. However, as our telescopes continued to improve, we have discovered that galaxies are instead dynamic systems,

Simulating molecular cloud regulated star formation in Galaxies [PDF]

, 2007
This thesis is primarily concerned with understanding the process of galaxy formation via the simulation of the interstellar medium, star formation and supernova feedback.

Revisiting the Gas Dynamics of Henize 2–10: Possible Drivers of the Starburst

The Astrophysical Journal
The triggers of starburst episodes are a key component to our understanding of the baryon cycle in galaxies. Galaxy mergers are a commonly suggested catalyst for starbursts, but once the galaxies coalesce into a single kinematically disturbed system ...

SO in starburst galaxies

The Astrophysical Journal, 1992
The use of SO and SO2 as probes of the dense interstellar medium in the nearby starburst galaxies NGC 253 and M82 is described. Emission in the 99.3 GHz 3(2) - 2(1) rotational transition of SO was detected in NGC 253 and possibly in M82, and upper limits are reported for emission in the 219.9 GHz 6(5) - 5(4) transition of SO and two lines of SO2.

The Calibration of Polycyclic Aromatic Hydrocarbon Dust Emission as a Star Formation Rate Indicator in the AKARI NEP Survey

The Astrophysical Journal
Polycyclic aromatic hydrocarbon (PAH) dust emission has been proposed as an effective extinction-independent star formation rate (SFR) indicator in the mid-infrared, but this may depend on conditions in the interstellar medium.

Starburst galaxies in the Hydra I cluster

Astronomy & Astrophysics
Studying the impact of environment on star formation and quenching pathways requires statistically relevant samples of galaxies in a wide mass range. We present a new catalog of 196 galaxies of the nearby Hydra I cluster out to ∼1.75r200, consisting of ...
