Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have revealed an extremely distant and therefore very young galaxy that looks surprisingly like our Milky Way. The results are...

An NSF-supported team of astronomers found new evidence of the occurrence of a kilonova -- a cosmic explosion that creates massive amounts of gold and platinum -- that went unnoticed during initial ob...

For decades, astronomers have found distant galaxies by detecting the characteristic way their gas absorbs light from a bright quasar in the background. But efforts to observe the light emitted by the...
Dusty Star Formation in Extreme Environments: Galaxies and Galaxy Clusters in the Distant Universe

In this thesis, we present a comprehensive study of the dust-obscured star formation (SF) activity in galaxy clusters out to high redshift using infrared (IR) imaging. Using hundreds of galaxy cluster...

The distant outskirts of the Milky Way harbor valuable clues for understanding the formation and evolution of our Galaxy. Yet, due to overwhelming distances and an extremely sparse population of star...
We present photometric and spectroscopic observations of the members of three previously cataloged compact group (CG) candidates at redshifts z>0.3. These confirm spectroscopic redshifts compatible wi...

Interpretation of the Global Anisotropy in the Radio Polarizations of Cosmologically Distant Sources
Polarization magnetic fields galaxies:active galaxies: high-redshift cosmology:miscellaneous elementary particles

We present a detailed statistical study of the observed
anisotropy in radio polarizations from distant extragalactic objects. This
anisotropy was earlier found by Birch (1982) and reconfirmed by Jai...
