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

The 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

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).
