SAGAbg II: the Low-Mass Star-Forming Sequence Evolves Significantly Between 0.05<z<0.21

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Erin Kado-Fong, Marla Geha, Yao-Yuan Mao, Mithi A. C. de los Reyes, Risa H. Wechsler | Summary: The redshift-dependent relation between galaxy stellar mass and star formation rate (the Star-Forming Sequence, or SFS) is a key observational yardstick for galaxy assembly. We use the SAGAbg-A sample […]

Evaluating probabilistic and data-driven inference models for fiber-coupled NV-diamond temperature sensors

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Shraddha Rajpal, Zeeshan Ahmed, Tyrus Berry, , | Summary: We evaluate the impact of inference model on uncertainties when using continuous wave Optically Detected Magnetic Resonance (ODMR) measurements to infer temperature. Our approach leverages a probabilistic feedforward inference model designed to maximize the likelihood of observed ODMR […]

The overestimation of equipartition magnetic field strengths from synchrotron emission using synthetically observed galaxies

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 […]

Enhancing Direct Detection of Higgsino Dark Matter

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 […]
