Kavli Affiliate: Susan E. Clark | First 5 Authors: Tara Dacunha, Sergio Martin-Alvarez, Susan E. Clark, Enrique Lopez-Rodriguez, | Summary: Understanding the role that magnetic fields play on the stage of galaxy formation requires accurate methods for inferring the properties of extragalactic magnetic fields. Radio synchrotron emission has been the most promising avenue to infer […]

Kavli Affiliate: Susan E. Clark | First 5 Authors: Emily K. Biermann, Yaqiong Li, Sigurd Naess, Steve K. Choi, Susan E. Clark | Summary: We conduct a systematic search for astrophysical transients using data from the Atacama Cosmology Telescope (ACT). The data were taken from 2017 to 2022 in three frequency bands spanning 77 GHz […]

Kavli Affiliate: Peter W. Graham | First 5 Authors: Peter W. Graham, Harikrishnan Ramani, Samuel S. Y. Wong, , | Summary: While much supersymmetric WIMP parameter space has been ruled out, one remaining important candidate is Higgsino dark matter. The Higgsino can naturally realize the “inelastic dark matter" scenario, where the scattering off a nucleus […]

Kavli Affiliate: Patricia Burchat | First 5 Authors: Ismael Mendoza, Andrii Torchylo, Thomas Sainrat, Axel Guinot, Alexandre Boucaud | Summary: We present an open source Python library for simulating overlapping (i.e., blended) images of galaxies and performing self-consistent comparisons of detection and deblending algorithms based on a suite of metrics. The package, named Blending Toolkit […]

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Vincent Chambouleyron, Mahawa Cissé, Maïssa Salama, Sebastiaan Haffert, Vincent Déo | Summary: The Zernike wavefront sensor (ZWFS) stands out as one of the most sensitive optical systems for measuring the phase of an incoming wavefront, reaching photon efficiencies close to the fundamental limit. This quality, combined with […]

Kavli Affiliate: Risa Wechsler | First 5 Authors: Mithi A. C. de los Reyes, Yasmeen Asali, Risa Wechsler, Marla Geha, Yao-Yuan Mao | Summary: The stellar masses of galaxies are measured using integrated light via several methods — however, few of these methods were designed for low-mass ($M_{star}lesssim10^{8}rm{M_{odot}}$) "dwarf" galaxies, whose properties (e.g., stochastic star […]

Kavli Affiliate: Laura Schaefer | First 5 Authors: Frances E. Rigby, Lorenzo Pica-Ciamarra, Måns Holmberg, Nikku Madhusudhan, Savvas Constantinou | Summary: The recent JWST detections of carbon-bearing molecules in a habitable-zone sub-Neptune have opened a new era in the study of low-mass exoplanets. The sub-Neptune regime spans a wide diversity of planetary interiors and atmospheres […]

Kavli Affiliate: Eric Charles | First 5 Authors: Qianjun Hang, Benjamin Joachimi, Eric Charles, John Franklin Crenshaw, Patricia Larsen | Summary: We investigate the impact of spatial survey non-uniformity on the galaxy redshift distributions for forthcoming data releases of the Rubin Observatory Legacy Survey of Space and Time (LSST). Specifically, we construct a mock photometry […]

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: The BICEP/Keck Collaboration, :, Y. Nakato, P. A. R. Ade, Z. Ahmed | Summary: Measurements of B-mode polarization in the CMB sourced from primordial gravitational waves would provide information on the energy scale of inflation and its potential form. To achieve these goals, one must carefully characterize […]
