Ionization Structure and Metal Enrichment of the Galactic Center Minispiral Observed with JWST
Nicole M Ford, Mayura Balakrishnan, Sebastiano D. von Fellenberg +11
Sagittarius A* (Sgr A*) is the nearest quiescent supermassive black hole, and its proximity offers a unique opportunity to study its surrounding fuel supply. We leverage extensive…
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…
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…
