Mapping dark matter in the Bullet Cluster using JWST imaging and spectroscopy
Gregor RihtarÅ¡iÄ, MaruÅ¡a BradaÄ, Guillaume Desprez +23
We present an updated gravitational lens model of the Bullet cluster (1E 0657-56) by combining JWST NIRCam imaging and NIRSpec spectroscopy. Although previous lens models relied on…
Accelerated calibration of semi-analytic galaxy formation models
Andrew Robertson, Andrew Benson
We present an accelerated calibration framework for semi-analytic galaxy formation models, demonstrated with Galacticus. Rather than fitting directly to properties such as the low-…
Star Formation under a Cosmic Microscope: Highly magnified z = 11 galaxy behind the Bullet Cluster
MaruÅ¡a BradaÄ, Jon Judež, Chris Willott +20
We present measurements of stellar population properties of a newly discovered spectroscopically confirmed , gravitationally lensed galaxy, using JWST NIRS…
Jeans Model for the Shapes of Self-interacting Dark Matter Halos
Yilber Fabian Bautista, Andrew Robertson, Laura Sagunski +2
The Jeans model is a semi-analytical approach to modeling self-interacting dark matter (SIDM) that works remarkably well to reproduce the spherically-averaged halo profiles from ob…
A deep dive down the broad-line region: permitted OI, CaII and FeII emission in an AGN Little Red Dot at z=5.3
Roberta Tripodi, MaruÅ¡a BradaÄ, Francesco D'Eugenio +27
We present a spectroscopic analysis of a broad-line active galactic nucleus (AGN) selected as little red dot at behind the Bullet cluster (Bz5.3), based on JWST/NIRCam an…
