The Black Hole Mass of Abell 1836-BCG and Abell 3565-BCG

, 2007
Two brightest cluster galaxies (BCGs), namely Abell 1836-BCG and Abell 3565-BCG, were observed with the Advanced Camera for Surveys (ACS) and the Space Telescope Imaging Spectrograph (STIS) on board the Hubble Space Telescope.

Constraining Star Formation in M87 Using Deep Hubble Space Telescope UV Data

The Astrophysical Journal
We analyzed the deepest Hubble Space Telescope F275W ultraviolet (UV) imaging of M87 to obtain the most robust constraints on its star formation rate (SFR) and star formation history (SFH).

HST Study of the Proper Motion of HST-1 in the Jet of M87

The Astrophysical Journal
The radio galaxy M87 is well known for its jet, which features a series of bright knots observable from radio to X-ray wavelengths. The most famous of these, HST-1, exhibits superluminal motion, and our analysis of Chandra data reveals a correlation ...

The Leakage of Lyman-continuum Photons from a Major Merger at z ∼ 1

The Astrophysical Journal
We report the detection of Lyman-continuum (LyC) photons from a massive interacting system at z = 1.097 in the Hubble Ultra Deep Field. The LyC detection is made in the far-ultraviolet F154W band of the UVIT telescope on board AstroSat.
