Kavli Affiliate: Anna Frebel | First 5 Authors: Jeremy Kowkabany, Rana Ezzeddine, Corinne Charbonnel, Ian U. Roederer, Ella Xi Wang | Summary: We present the discovery of 2MASS J05241392-0336543 (hereafter J0524-0336), a very metal-poor ([Fe/H]=-2.43 +- 0.16), highly r-process-enhanced ([Eu/Fe]= +1.34 +- 0.10) Milky Way halo field red giant star, with an ultra high Li […]
Kavli Affiliate: David N. Spergel | First 5 Authors: Digvijay Wadekar, Leander Thiele, J. Colin Hill, Shivam Pandey, Francisco Villaescusa-Navarro | Summary: Ionized gas in the halo circumgalactic medium leaves an imprint on the cosmic microwave background via the thermal Sunyaev-Zeldovich (tSZ) effect. Feedback from active galactic nuclei (AGN) and supernovae can affect the measurements […]
Kavli Affiliate: David N. Spergel | First 5 Authors: Digvijay Wadekar, Leander Thiele, J. Colin Hill, Shivam Pandey, Francisco Villaescusa-Navarro | Summary: Feedback from active galactic nuclei (AGN) and supernovae can affect measurements of integrated SZ flux of halos ($Y_mathrm{SZ}$) from CMB surveys, and cause its relation with the halo mass ($Y_mathrm{SZ}-M$) to deviate from […]
Kavli Affiliate: Edward W. Kolb | First 5 Authors: Edward Basso, Daniel J. H. Chung, Edward W. Kolb, Andrew J. Long, | Summary: Previous numerical investigations of gravitational particle production during the coherent oscillation period of inflation displayed unexplained fluctuations in the spectral density of the produced particles. We argue that these features are due […]
Kavli Affiliate: Ke Wang | First 5 Authors: Zhuo Chen, Jie Liu, Yubo Hu, Lei Wu, Yajin Zhou | Summary: In recent years, the underground economy is proliferating in the mobile system. These underground economy apps (UEware) make profits from providing non-compliant services, especially in sensitive areas such as gambling, pornography, and loans. Unlike traditional […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Zhijie Qu, Hsiao-Wen Chen, Gwen C. Rudie, Fakhri S. Zahedy, Sean D. Johnson | Summary: This paper presents a systematic study of the photoionization and thermodynamic properties of the cool circumgalactic medium (CGM) as traced by rest-frame ultraviolet absorption lines around 26 galaxies at redshift $zlesssim1$. […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Brittany E. Miles, Beth A. Biller, Polychronis Patapis, Kadin Worthen, Emily Rickman | Summary: We present the highest fidelity spectrum to date of a planetary-mass object. VHS 1256 b is a $<$20 M$_mathrm{Jup}$ widely separated ($sim$8arcsec, a = 150 au), young, planetary-mass companion that shares photometric colors […]
Kavli Affiliate: Jeffrey J. McMahon | First 5 Authors: Johannes Hubmayr, Jason E. Austermann, James A. Beall, Jake A. Connors, Shannon M. Duff | Summary: Planar Orthomode Transducers (OMTs) are commonly used for polarization measurements at millimeter wavelengths. We present an optical coupling study of an octave bandwidth planar OMT in circular waveguide based on […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Aarynn L. Carter, Sasha Hinkley, Jens Kammerer, Andrew Skemer, Beth A. Biller | Summary: We present JWST Early Release Science (ERS) coronagraphic observations of the super-Jupiter exoplanet, HIP 65426 b, with the Near-Infrared Camera (NIRCam) from 2-5 $mu$m, and with the Mid-Infrared Instrument (MIRI) from 11-16 $mu$m. […]
