Extragalactic Magnetism with SOFIA (Legacy Program) — I: The magnetic field in the multi-phase interstellar medium of M51

Posted by klaurent May 19, 2021Stanford

Kavli Affiliate: Susan E. Clark | First 5 Authors: Alejandro S. Borlaff, Enrique Lopez-Rodriguez, Rainer Beck, Rodion Stepanov, Eva Ntormousi | Summary: The recent availability of high-resolution far-infrared (FIR) polarization observations of galaxies using HAWC+/SOFIA has facilitated studies of extragalactic magnetic fields in the cold and dense molecular disks.We investigate if any significant structural differences […]

“Worst-Case” Micro-Lensing in the Identification and Modeling of Lensed Quasars

Posted by dbos May 18, 2021MIT

Kavli Affiliate: Paul Schechter | First 5 Authors: Luke Weisenbach, Paul Schechter, Sahil Pontula, , | Summary: Although micro-lensing of macro-lensed quasars and supernovae provides unique opportunities for several kinds of investigations, it can add unwanted and sometimes substantial noise. While micro-lensing flux anomalies may be safely ignored for some observations, they severely limit others. […]

Revisiting CMB constraints on dark matter annihilation

Posted by klaurent May 18, 2021Tokyo

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Hiromasa Nakatsuka, Kazunori Nakayama, Toyokazu Sekiguchi, | Summary: The precision measurements of the cosmic microwave background power spectrum put a strong constraint on the dark matter annihilation cross section since the electromagnetic energy injection by the dark matter annihilation affects the ionization history of the […]

Joint Optimization of Hadamard Sensing and Reconstruction in Compressed Sensing Fluorescence Microscopy

Posted by May 17, 2021Cornell

Kavli Affiliate: Chris Xu | First 5 Authors: Alan Q. Wang, Aaron K. LaViolette, Leo Moon, Chris Xu, Mert R. Sabuncu | Summary: Compressed sensing fluorescence microscopy (CS-FM) proposes a scheme whereby less measurements are collected during sensing and reconstruction is performed to recover the image. Much work has gone into optimizing the sensing and […]
