Photometric Constraints on Intermediate-mass Black Holes in the Galactic Centre
Tamojeet Roychowdhury, Sebastiano D. von Fellenberg, Joseph M. Michail +14
JWST/MIRI observations can place photometric limits on the presence of an intermediate-mass black hole (IMBH) near the Galactic Centre. The stellar complex IRS 13E, a co-moving con…
First Mid-infrared Detection and Modeling of a Flare from Sgr A*. II. Mid-IR Spectral Energy Distribution and Millimeter Polarimetry
Joseph M. Michail, Sebastiano D. von Fellenberg, Garrett K. Keating +20
S. D. von Fellenberg et al. (2025a, Paper I) reported the first mid-infrared detection of a flare from Sgr A*. The JWST/MIRI/MRS observations were consistent with an orbiting hotsp…
A Supermassive Black Hole in a Diminutive Ultra-compact Dwarf Galaxy Discovered with JWST/NIRSpec+IFU
Matthew A. Taylor, Behzad Tahmasebzadeh, Solveig Thompson +18
The integral-field unit mode of the Near-Infrared Spectrograph (NIRSpec+IFU) mounted on the James Webb Space Telescope has now enabled kinematic studies of smaller and less massive…
First mid-infrared detection and modeling of a flare from Sgr A*
Sebastiano D. von Fellenberg, Tamojeet Roychowdhury, Joseph M. Michail +24
The time-variable emission from the accretion flow of Sgr A*, the supermassive black hole at the Galactic Center, has long been examined in the radio-to-mm, near-infrared (NIR), an…
