A Study on Quenching and Galaxy Growth in z~1 Clusters using HST WFC3 Grism Observations
… infrared F140W imaging and G141 grism data on 10 galaxy clusters at $z\sim1$ to study how the quenching of star formation in galaxies and galaxy size growth operates in different environments at this redshift. The unique capabilities of space-based slitless spectroscopy with the G141 grism allows …

Constraining the Major Merging History of Massive Galaxies: A Comprehensive Analysis of Close Pairs and Tidal Features Using Empirical and Simulated Data
Major galaxy merging is a fundamental aspect of the hierarchical structure-growth scenario of the universe, and it is theoretical expected to contribute to several key aspects of galaxy evolution. As such, empirically identifying major mergers is a key methodological step towards assessing the …

Heart of darkness
… from behemoths in the cores of almost every galaxy to more modest, stellar-mass objects spattering the Milky Way's arms. Astronomers suspect that super massive black holes like Sagittarius A* (the compact dark object at the center of our galaxy) may be a cosmic mafia manipulating the galaxies …
