VLBA reveals the absence of a compact radio core in the radio intermediate quasar J2242+0334 at z =5.9

Kavli Affiliate: Ran Wang | First 5 Authors: Yuanqi Liu, Ran Wang, Emmanuel Momjian, Yingkang Zhang, Tao An | Summary: High-resolution imaging is crucial for exploring the origin and mechanism of radio emission in quasars, especially at high redshifts. We present 1.5 GHz Very Long Baseline Array (VLBA) images of the radio continuum emission from […]

What does an interferometer really measure? Including instrument and data characteristics in the reconstruction of the 21cm power spectrum

Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Adélie Gorce, Samskruthi Ganjam, Adrian Liu, Steven G. Murray, Zara Abdurashidova | Summary: Combining the visibilities measured by an interferometer to form a cosmological power spectrum is a complicated process in which the window functions play a crucial role. In a delay-based analysis, the mapping between […]

The hidden side of cosmic star formation at z > 3: Bridging optically-dark and Lyman break galaxies with GOODS-ALMA

Kavli Affiliate: John Silverman | First 5 Authors: Mengyuan Xiao, David Elbaz, Carlos Gómez-Guijarro, Lucas Leroy, Longji Bing | Summary: Our current understanding of the cosmic star formation history at z>3 is primarily based on UV-selected galaxies (i.e., LBGs). Recent studies of H-dropouts revealed that we may be missing a large amount of star formation […]

Eccentricity to the rescue! Detecting Accelerating Eccentric Binaries in the LISA Band

Kavli Affiliate: Xian Chen | First 5 Authors: Zeyuan Xuan, Smadar Naoz, Xian Chen, , | Summary: Many gravitational wave (GW) sources in the LISA band are expected to have non-negligible eccentricity. Furthermore, many of them can undergo acceleration because they reside in the presence of a tertiary. Here we develop analytical and numerical methods […]
