First Statistical Study of Over 100 Magnified Stellar Events at Redshift with JWST
J. M. Palencia, Fengwu Sun, J. M. Diego +25
Highly magnified stars at cosmological distances () become detectable thanks to microlensing by intracluster stars near the critical curves of galaxy clusters. Multi…
JWST lens model for A370: A very low dark matter fraction for a brightest cluster galaxy and lensing properties for the Dragon arc
Jose M. Diego, Fengwu Sun, Jose M. Palencia +8
We present a new lens model for the galaxy cluster Abell 370 based on previously spectroscopically confirmed lensed galaxies and new lensed systems identified in JWST dat…
Imaging dark matter at the smallest scales with lensed stars
J. M. Diego, Sung Kei Li, Alfred Amruth +19
Observations of caustic-crossing galaxies at redshift show a wealth of transient events. Most of them are believed to be microlensing events of highly magnified stars. Ea…
BUFFALO/Flashlights: Constraints on the abundance of lensed supergiant stars in the Spock galaxy at redshift 1
Jose M. Diego, Sung Kei Li, Ashish K. Meena +27
We present a constraint on the abundance of supergiant (SG) stars at redshift z approx. 1, based on recent observations of a strongly lensed arc at this redshift. First we derive a…
Coma Cluster Ultra-Diffuse Galaxies Are Not Standard Radio Galaxies
Mitchell F. Struble
Matching members in the Coma cluster catalogue of ultra-diffuse galaxies (UDGs, Yagi et al. 2016) from SUBARU imaging with a very deep radio continuum survey source catalogue of th…
Observed Bimodality of the Einstein Crossing Times of Galactic Microlensing Events
T. Wickramasinghe, M. Struble, J. Nieusma
The OGLE data for Einstein ring crossing times, , for microlensing events toward the galactic bulge are analyzed. The analysis shows that the crossing times are bimodal, i…
