Under Einstein's Microscope: Measuring Properties of Individual Rotating Massive Stars From Extragalactic Micro Caustic Crossings
Xu Han, Liang Dai
Highly magnified stars residing in caustic crossing lensed galaxies at z ~ 0.7-1.5 in galaxy cluster lensing fields inevitably exhibit recurrent brightening events as they traverse…
Dissecting the Stochastic Gravitational Wave Background with Astrometry
Mesut Çalışkan, Yifan Chen, Liang Dai +3
Astrometry, the precise measurement of star motions, offers an alternative avenue to investigate low-frequency gravitational waves through the spatial deflection of photons, comple…
The JWST Discovery of the Triply-imaged Type Ia "Supernova H0pe" and Observations of the Galaxy Cluster PLCK G165.7+67.0
Brenda L. Frye, Massimo Pascale, Justin Pierel +39
A Type Ia supernova (SN) at was discovered in James Webb Space Telescope Near Infrared Camera imaging of the galaxy cluster PLCK G165.7+67.0 (G165; ). The SN is…
JWST's PEARLS: Mothra, a new kaiju star at z=2.091 extremely magnified by MACS0416, and implications for dark matter models
J. M. Diego, Bangzheng Sun, Haojing Yan +28
We report the discovery of Mothra, an extremely magnified monster star, likely a binary system of two supergiant stars, in one of the strongly lensed galaxies behind the galaxy clu…
Spectroscopy of the Supernova H0pe Host Galaxy at Redshift 1.78
M. Polletta, M. Nonino, B. Frye +42
Supernova (SN) H0pe was discovered as a new transient in James Webb Space Telescope (JWST) NIRCam images of the galaxy cluster PLCK G165.7+67.0 taken as part of the "Prime Extragal…
Testing charge quantization with axion string-induced cosmic birefringence
Weichen Winston Yin, Liang Dai, Simone Ferraro
We demonstrate that the Peccei-Quinn-electromagnetic anomaly coefficient can be directly measured from axion string-induced cosmic birefringence by applying scattering…
Magnetic Fields from Compensated Isocurvature Perturbations
Jordan Flitter, Cyril Creque-Sarbinowski, Marc Kamionkowski +1
Compensated isocurvature perturbations (CIPs) are perturbations to the primordial baryon density that are accompanied by dark-matter-density perturbations so that the total matter…
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…
Wave Mechanics, Interference, and Decoherence in Strong Gravitational Lensing
Calvin Leung, Dylan Jow, Prasenjit Saha +3
Wave-mechanical effects in gravitational lensing have long been predicted, and with the discovery of populations of compact transients such as gravitational wave events and fast ra…
Detecting Strong Gravitational Lensing of Gravitational Waves with TianQin
Xin-yi Lin, Jian-dong Zhang, Liang Dai +2
When gravitational waves (GWs) pass by a massive object on its way to Earth, a strong gravitational lensing effect will happen. Thus, the GW signal will be amplified, deflected, an…
Paper 1: The JWST PEARLS View of the El Gordo Galaxy Cluster and of the Structure It Magnifies
Brenda L. Frye, Massimo Pascale, Nicholas Foo +41
The massive galaxy cluster El Gordo (z=0.87) imprints multitudes of gravitationally lensed arcs onto James Webb Space Telescope (JWST) Near-Infrared Camera (NIRCam) images. Eight b…
Nitrogen-enriched, highly-pressurized nebular clouds surrounding a super star cluster at cosmic noon
Massimo Pascale, Liang Dai, Christopher F. McKee +1
Strong lensing offers a precious opportunity for studying the formation and early evolution of super star clusters that are rare in our cosmic backyard. The Sunburst Arc, a lensed…
