Jashanpreet Singh Dingra / astrodingra
Status: MSc Physics (FYIP) @ Guru Nanak Dev University, Amritsar.
Focus: AGN feedback, High-z galaxies, Galaxy morphology, Machine learning.
Roles: Founder of Dingrastro Club, ISRO Space Tutor, Astropy contributor, Founder & CTO of Sitee.
I study how supermassive black holes shape the galaxies around them. I use JWST observations and cosmological simulations like IllustrisTNG and EAGLE to follow early-universe galaxies forward in time, and I build open-source pipelines and ML tools to do it at scale.
Now
# tracing JWST "Little Red Dots" to z=0 in IllustrisTNG (w/ MPIA Heidelberg)
# AGN multiwavelength study in SDSS (w/ Copernicus Center, Warsaw)
# shipping Galamo, Galspar, RAGA, vdisp_fit
# building Sitee and Brepline
Publications
Manuscripts under review and ongoing international work.
A Unified Deep Learning Framework for Automated Morphological Classification and Photometric Analysis using DECaLS Legacy Imaging
Powers Galamo, an open-source package for morphology, kinematics, photometry and spectra. [galamo.org]
Black hole mass and galaxy dynamics in Seyfert Type II and LINER galaxies
First presentation of the MBH-σ correlation for Seyfert Type II, despite obscuration from the nuclear dust and torus.
The Evolutionary Destiny and Observational Deficits of JWST "Little Red Dot" Analogues in IllustrisTNG
Tracked to z=0, these anomalies look like the direct progenitors of today's massive BCGs, and radiatively efficient AGN feedback explains their rapid quenching. Supported by an IUCAA Pegasus Cluster computing grant.
