Photometry of Compact Galaxies
The Astrophysical Journal, 1972 Photometric histories of the N galaxies 3C 390.3 and PKS 0521-36. Four other compact galaxies, Markarian 9, I Zw 92, 2 Zw 136, and III Zw 77 showed no evidence of variability. The photometric histories were obtained from an exhaustive study of those plates of the Harvard collection taken with large aperture cameras. The images of all galaxies reported

The extended structure of the dwarf irregular galaxy Sagittarius [PDF]
, 2014 We present a detailed study of the stellar and HI structure of the dwarf irregular galaxy Sagittarius. We use new deep and wide field photometry to trace the surface brightness profile of the galaxy out to ~5.0' (corresponding to ~1600 pc) and down to ...

Spatially Resolved Recent Star Formation History in NGC 6946
The Astrophysical Journal, 2023 The nearby face-on star-forming spiral galaxy NGC 6946 is known as the Fireworks Galaxy due to its hosting an unusually large number of supernovae. We analyze its resolved near-ultraviolet stellar photometry measured from images taken with the Hubble ...

SN 2016hil-- a Type II supernova in the remote outskirts of an elliptical host and its origin [PDF]
, 2019 Type II supernovae (SNe) stem from the core collapse of massive ($>8\ M_{\odot}$) stars. Owing to their short lifespan, we expect a very low rate of such events in elliptical host galaxies, where the star-formation rate is low, and which mostly consist ...

Spitzer Observations of the z=2.73 Lensed Lyman Break Galaxy, MS1512-cB58 [PDF]
, 2008 We present Spitzer infrared (IR) photometry and spectroscopy of the lensed Lyman break galaxy (LBG), MS1512-cB58 at z=2.73. The large (factor ~30) magnification allows for the most detailed infrared study of an L*_UV(z=3) LBG to date.

, 2019 Extragalactic surveys provide significant statistical data for the study of crucial galaxy parameters used to constrain galaxy evolution, e.g. stellar mass (M$_*$) and star formation rate (SFR), under different environmental conditions.

SGAS 143845.1+145407: A Big, Cool Starburst at Redshift 0.816 [PDF]
, 2012 We present the discovery and a detailed multi-wavelength study of a strongly-lensed luminous infrared galaxy at z=0.816. Unlike most known lensed galaxies discovered at optical or near-infrared wavelengths this lensed source is red, r-Ks = 3.9 [AB ...

Stochastic 2-D Galaxy disk Evolution Models. Resolved Stellar Populations in the Galaxy M33
Open Astronomy, 2015 We improved the stochastic 2-D galaxy disk models (Mineikis & Vansevičius 2014a) by introducing enriched gas outflows from galaxies and synthetic color-magnitude diagrams of stellar populations.
