The properties of discrete X-ray sources in star-forming galaxies [PDF]
, 2012 Observations of starburst galaxies have revealed a large number of point-like X-ray sources located within these systems, including active galactic nuclei (AGN), X-ray binaries (XRBs), and utraluminous X-ray sources (ULXs).

The Karl G. Jansky Very Large Array Local Group L-Band Survey (LGLBS)
The Astrophysical Journal Supplement SeriesWe present the Local Group L -Band Survey, a Karl G. Jansky Very Large Array (VLA) survey producing the highest-quality 21 cm and 1–2 GHz radio continuum images to date, for the six VLA-accessible, star-forming, Local Group galaxies. Leveraging the VLA’s

Groups, clusters and superclusters of galaxies [PDF]
, 1991 Galaxies are observed in a diverse range of associations. Understanding the dynamical, statistical and clustering properties of aggregations of galaxies forms the main body of this thesis.

Ionized interstellar froth in irregular galaxies [PDF]
, 1990 The warm interstellar medium of galaxies is a complicated place. It is often full of holes, neutral and ionized loops and shells, and diffuse ionized gas.

Pressure and Star Formation in LITTLE THINGS Dwarf Irregular Galaxies
The Astrophysical JournalThe surface densities of star formation, Σ _SFR , in 24 dwarf irregular (dIrr) galaxies from the LITTLE THINGS survey are combined with gas surface densities and midplane pressures to examine the correlations found previously for spiral galaxies.

Empirical Dependencies for Irregular and Elliptical Dwarf Galaxies
Moscow University Physics BulletinThis study examines the physical properties and correlations for dwarf galaxies, including irregular (dIrr) and elliptical (dE) types. Data from the NASA/IPAC and HyperLEDA databases were used to analyze relationships among parameters such as distance to galaxy, absolute magnitude of galaxy, mass of galaxy, and surface brightness of galaxy using ...

The clustering of dark matter, haloes & galaxies [PDF]
, 2008 In this thesis I study the spatial distribution of galaxies, haloes and dark matter particles using a suite of state-of-art cosmological N-body simulations of the growth structure in the Universe.

Spatially resolved spectroscopy of faint star-forming galaxies & their environments in the high redshift universe [PDF]
, 2011 This thesis is concerned with the spectroscopic observations of distant galaxies, 1 < z < 5. The galaxies presented here are intrinsically faint such that their ux is dominated by ordinary star formation rather than galaxy-galaxy merging and/or ...

Post-starburst Galaxies in SDSS-IV MaNGA: Two Broad Categories of Evolutionary Pathways
The Astrophysical JournalWe study the size–mass relation (SMR) and recent star formation history (SFH) of post-starburst (PSB) galaxies in the local Universe using spatially resolved spectroscopy from the final data release of MaNGA. Our sample includes 489 PSB galaxies: 94 cPSB
