Using Scattered Near-Infrared Light to Map Water Ice in Prestellar Cores with SPHEREx
Tamojeet Roychowdhury, Jennifer B. Bergner, Jens Kauffmann +2
We present the first coreshine-derived, spatially-resolved maps of the 3 m HO ice absorption feature in four prestellar cores, using SPHEREx spectra. Ices are a key compone…
A Statistical Framework to Identify Kinematically Outlying LMC Globular Clusters and Implications for the LMC's Dark Matter Profile
Tamojeet Roychowdhury, Navdha, Himansh Rathore +1
The authors develop a statistical method that combines Gaia‑DR3 proper motions with line‑of‑sight velocities to identify kinematically outlying globular clusters in the Large Magel…
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…
SPURS: Evidence for Clumpy Neutral Envelopes and Ionized IGM Surrounding Little Red Dots in Abell 2744 from Ultra-Deep Rest-UV Spectroscopy
Mengtao Tang, Daniel P. Stark, Charlotte A. Mason +14
Rest-frame ultraviolet (UV) spectra of Little Red Dots (LRDs) often show Ly emission. Along with broad Balmer emission, LRDs are expected to produce broad Ly emission. Howe…
Possible Extragalactic Origins of Five LMC Globular Clusters: Proper Motion Deviations in Gaia DR3
Tamojeet Roychowdhury, Navdha Bhalla
We use kinematic data of proper motions from Gaia of forty-two globular and open clusters from Large Magellanic Cloud (LMC) to explore the possibility of them having extragalactic…
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…
