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…
Seeking Kinematic Association of Known FU Orionis Stars with Young Clusters in Cygnus
Tamojeet Roychowdhury, Lynne A. Hillenbrand
Kinematic studies of young stars and star clusters have increased our understanding of the process of star formation and evolution in the Milky Way. FU Orionis objects are a specif…
Efficacy of Galaxy Catalogues for following up gravitational wave events
Tamojeet Roychowdhury, Harsh Choudhary, Varun Bhalerao +6
The detection of gravitational waves (GW) by the LIGO-Virgo-KAGRA (LVK) network has opened up a new era in astrophysics. The identification of the electromagnetic counterparts of G…
Fixed-Confidence Best Arm Identification with Decreasing Variance
Tamojeet Roychowdhury, Kota Srinivas Reddy, Krishna P Jagannathan +1
We focus on the problem of best-arm identification in a stochastic multi-arm bandit with temporally decreasing variances for the arms' rewards. We model arm rewards as Gaussian ran…
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…
