Time-resolved Hubble Space Telescope UV Observations of an X-Ray Quasiperiodic Eruption Source

open access: yesThe Astrophysical Journal Letters
X-ray quasiperiodic eruptions (QPEs) are a novel mode of variability in nearby galactic nuclei whose origin remains unknown. Their multiwavelength properties are poorly constrained, as studies have focused almost entirely on the X-ray band.

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

open access: yesThe 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

open access: yesThe 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 ...
