Characterization of MKIDs for CMB observation at 220 GHz with the South Pole Telescope

Kavli Affiliate: Bradford A. Benson | First 5 Authors: Karia R. Dibert, Peter S. Barry, Adam J. Anderson, Bradford A. Benson, Thomas Cecil | Summary: We present an updated design of the 220 GHz microwave kinetic inductance detector (MKID) pixel for SPT-3G+, the next-generation camera for the South Pole Telescope. We show results of the […]

200,000 Candidate Very Metal-poor Stars in Gaia DR3 XP Spectra

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Yupeng Yao, Alexander P. Ji, Sergey E. Koposov, Guilherme Limberg, | Summary: Very metal-poor stars ($rm[Fe/H] < -2$) in the Milky Way are fossil records of early chemical evolution and the assembly and structure of the Galaxy. However, they are rare and hard to find. Gaia […]

Comparison of Polarized Radiative Transfer Codes used by the EHT Collaboration

Kavli Affiliate: Bradford A. Benson | First 5 Authors: Ben S. Prather, Jason Dexter, Monika Moscibrodzka, Hung-Yi Pu, Thomas Bronzwaer | Summary: Interpretation of resolved polarized images of black holes by the Event Horizon Telescope (EHT) requires predictions of the polarized emission observable by an Earth-based instrument for a particular model of the black hole […]

Absorption of Vector Dark Matter Beyond Kinetic Mixing

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Gordan Krnjaic, Tanner Trickle, , , | Summary: Massive vector particles are minimal dark matter candidates that motivate a wide range of laboratory searches, primarily exploiting a postulated kinetic mixing with the photon. However, depending on the high energy field content, the dominant vector dark matter (VDM) […]

Simulating image coaddition with the Nancy Grace Roman Space Telescope: II. Analysis of the simulated images and implications for weak lensing

Kavli Affiliate: Katrin Heitmann | First 5 Authors: Masaya Yamamoto, Katherine Laliotis, Emily Macbeth, Tianqing Zhang, Christopher M. Hirata | Summary: One challenge for applying current weak lensing analysis tools to the Nancy Grace Roman Space Telescope is that individual images will be undersampled. Our companion paper presented an initial application of Imcom – an […]
