Demonstration of hybrid foreground removal on CHIME data

Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Haochen Wang, Kiyoshi Masui, Kevin Bandura, Arnab Chakraborty, Matt Dobbs | Summary: The main challenge of 21 cm cosmology experiments is astrophysical foregrounds which are difficult to separate from the signal due to telescope systematics. An earlier study has shown that foreground residuals induced by antenna gain […]

Unveiling the Cosmic Chemistry: Revisiting the Mass-Metallicity Relation with JWST/NIRSpec at 4 < z < 10

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Arnab Sarkar, Priyanka Chakraborty, Mark Vogelsberger, Micheal McDoland, Paul Torrey | Summary: We present star formation rates (SFR), the mass-metallicity relation (MZR), and the SFR-dependent MZR across redshifts 4 to 10 using 81 star-forming galaxies observed by the JWST NIRSpec employing both low-resolution PRISM and medium-resolution gratings, […]

Mass determination of two Jupiter-sized planets orbiting slightly evolved stars: TOI-2420 b and TOI-2485 b

Kavli Affiliate: George Ricker | First 5 Authors: Ilaria Carleo, Oscar Barrágan, Carina M. Persson, Malcolm Fridlund, Kristine W. F. Lam | Summary: Hot and warm Jupiters might have undergone the same formation and evolution path, but the two populations exhibit different distributions of orbital parameters, challenging our understanding on their actual origin. The present […]

Proof of principle X-ray reflection mass measurement of the black hole in H1743-322

Kavli Affiliate: Erin Kara | First 5 Authors: Edward Nathan, Adam Ingram, James F. Steiner, Ole König, Thomas Dauser | Summary: The black hole X-ray binary H1743-322 lies in a region of the Galaxy with high extinction, and therefore it has not been possible to make a dynamical mass measurement. In this paper we make […]
