Evidence for a shock-compressed magnetic field in the northwestern rim of Vela Jr. from X-ray polarimetry

Kavli Affiliate: Nicola Omodei | First 5 Authors: Dmitry A. Prokhorov, Yi-Jung Yang, Riccardo Ferrazzoli, Jacco Vink, Patrick Slane | Summary: Synchrotron X-ray emission has been detected from nearly a dozen young supernova remnants (SNRs). X-rays of synchrotron origin exhibit linear polarization in a regular, non-randomly oriented magnetic field. The significant polarized X-ray emission from […]

Improving Galaxy Cluster Selection with the Outskirt Stellar Mass of Galaxies

Kavli Affiliate: Eli Rykoff | First 5 Authors: Matthew Kwiecien, Tesla Jeltema, Alexie Leauthaud, Song Huang, Eli Rykoff | Summary: The number density and redshift evolution of optically selected galaxy clusters offer an independent measurement of the amplitude of matter fluctuations, $S_8$. However, recent results have shown that clusters chosen by the redMaPPer algorithm show […]

Coronagraph-based wavefront sensors for the high Strehl regime

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Vincent Chambouleyron, J. Kent Wallace, Rebecca Jensen-Clem, Bruce Macintosh, | Summary: A crucial component of the high-contrast instrumental chain in astronomy is the wavefront sensor (WFS). A key property of this component is its sensitivities, which reflect its ability to efficiently use incoming photons to encode the […]

Correcting for Selection Biases in the Determination of the Hubble Constant from Time-Delay Cosmography

Kavli Affiliate: Philip J. Marshall | First 5 Authors: Tian Li, Thomas E. Collett, Philip J. Marshall, Sydney Erickson, Wolfgang Enzi | Summary: The time delay between multiple images of strongly lensed quasars has been used to infer the Hubble constant. The primary systematic uncertainty for time-delay cosmography is the mass-sheet transform (MST), which preserves […]
