Gravitational wave lensing as a probe of halo properties and dark matter
Giovanni Tambalo, Miguel Zumalacárregui, Liang Dai +1
Just like light, gravitational waves (GWs) are deflected and magnified by gravitational fields as they propagate through the Universe. However, their low frequency, phase coherence…
JWST's PEARLS: a new lens model for ACT-CL J01024915, "EL Gordo'', and the first red supergiant star at cosmological distances discovered by JWST
Jose M. Diego, Ashish K. Meena, Nathan J. Adams +27
The first JWST data on the massive colliding cluster El Gordo confirm 23 known families of multiply lensed images and identify 8 new members of these families. Based on these famil…
Lensing of gravitational waves: efficient wave-optics methods and validation with symmetric lenses
Giovanni Tambalo, Miguel Zumalacárregui, Liang Dai +1
Gravitational wave (GW) astronomy offers the potential to probe the wave-optics regime of gravitational lensing. Wave optics (WO) effects are relevant at low frequencies, when the…
JWST's PEARLS: Prime Extragalactic Areas for Reionization and Lensing Science: Project Overview and First Results
Rogier A. Windhorst, Seth H. Cohen, Rolf A. Jansen +82
We give an overview and describe the rationale, methods, and first results from NIRCam images of the JWST "Prime Extragalactic Areas for Reionization and Lensing Science" ("PEARLS"…
Unscrambling the lensed galaxies in JWST images behind SMACS0723
Massimo Pascale, Brenda L. Frye, Jose Diego +16
The first deep field images from the James Webb Space Telescope (JWST) of the galaxy cluster SMACS~J0723.3-7327 reveal a wealth of new lensed images at uncharted infrared wavelengt…
Detecting Cosmic Strings with Lensed Fast Radio Bursts
Huangyu Xiao, Liang Dai, Matthew McQuinn
Correlated red noise recently reported from pulsar timing observations may be an indication of stochastic gravitational waves emitted by cosmic strings that formed during a primord…
Godzilla, a monster lurks in the Sunburst galaxy
J. M. Diego, M. Pascale, B. J. Kavanagh +4
We model the strong lensing effect in the galaxy cluster PSZ1 G311.65-18.48 (z=0.443) with an improved version of the hybrid method WSLAP+. We extend the number of constraints by i…
Possible Ongoing Merger Discovered by Photometry and Spectroscopy in the Field of the Galaxy Cluster PLCK G165.7+67.0
Massimo Pascale, Brenda L. Frye, Liang Dai +17
We present a detailed study of the Planck-selected binary galaxy cluster PLCK G165.7+67.0 (G165; =0.348). A multiband photometric catalog is generated that incorporates new imag…
Snowmass2021 Cosmic Frontier White Paper: Dark Matter Physics from Halo Measurements
Keith Bechtol, Simon Birrer, Francis-Yan Cyr-Racine +41
The non-linear process of cosmic structure formation produces gravitationally bound overdensities of dark matter known as halos. The abundances, density profiles, ellipticities, an…
