Kavli Affiliate: Eric Charles | First 5 Authors: Celine Armand, Eric Charles, Mattia di Mauro, Chiara Giuri, J. Patrick Harding | Summary: Cosmological and astrophysical observations suggest that 85% of the total matter of the Universe is made of Dark Matter (DM). However, its nature remains one of the most challenging and fundamental open questions […]
Kavli Affiliate: Eli S. Rykoff | First 5 Authors: Hiroaki Aihara, Yusra AlSayyad, Makoto Ando, Robert Armstrong, James Bosch | Summary: The paper presents the third data release of Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP), a wide-field multi-band imaging survey with the Subaru 8.2m telescope. HSC-SSP has three survey layers (Wide, Deep, and UltraDeep) with […]
Kavli Affiliate: J. Todd Hoeksema | Summary:Both NASA’s Solar Dynamics Observatory (SDO) and the JAXA/NASA Hinode mission include spectropolarimetric instruments designed to measure the photospheric magnetic field. SDO’s Helioseismic and Magnetic Imager (HMI) emphasizes full-disk high-cadence and good spatial resolution data acquisition while Hinode’s Solar Optical Telescope Spectro-Polarimeter (SOT-SP) focuses on high spatial resolution and […]
Kavli Affiliate: Peter W. Graham | First 5 Authors: Michael A. Fedderke, Peter W. Graham, Derek F. Jackson Kimball, Saarik Kalia, | Summary: In our recent companion paper [arXiv:2106.00022], we pointed out a novel signature of ultralight kinetically mixed dark-photon dark matter. This signature is a quasi-monochromatic, time-oscillating terrestrial magnetic field that takes a particular […]
Kavli Affiliate: Laura Schaefer | First 5 Authors: Laura Schaefer, Vivien Parmentier, , , | Summary: Atmospheric compositions for rocky exoplanets will depend strongly on the bulk planetary composition and the orbital position of the planet. Non-traditional gases may be present in the atmospheres of exceptionally hot planets. Atmospheres of more clement planets will depend […]
Kavli Affiliate: Peter W. Graham | First 5 Authors: Dmitry Budker, Peter W. Graham, Harikrishnan Ramani, Ferdinand Schmidt-Kaler, Christian Smorra | Summary: We propose the use of trapped ions for detection of millicharged dark matter. Millicharged particles will scatter off the ions, giving a signal either in individual events or in the overall heating rate […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Federica B. Bianco, Željko Ivezić, R. Lynne Jones, Melissa L. Graham, Phil Marshall | Summary: Vera C. Rubin Observatory is a ground-based astronomical facility under construction, a joint project of the National Science Foundation and the U.S. Department of Energy, designed to conduct a multi-purpose 10-year […]
Kavli Affiliate: R. Morris | First 5 Authors: A. I. Harris, R. Güsten, M. A. Requena-Torres, D. Riquelme, M. R. Morris | Summary: We report SOFIA-upGREAT spectroscopic imaging of the [C II] 158um spectral line, as well as a number of [O I] 63um spectra, across a 67×45 pc field toward the Sgr B region […]
Kavli Affiliate: Susan E. Clark | First 5 Authors: Enrique Lopez-Rodriguez, Rainer Beck, Susan E. Clark, Annie Hughes, Alejandro S. Borlaff | Summary: Galactic bars are frequent in disk galaxies and they may support the transfer of matter towards the central engine of active nuclei. The barred galaxy NGC 1097 has magnetic forces controlling the […]
