Uncovering dark matter density profiles in dwarf galaxies with graph neural networks

Kavli Affiliate: Lina Necib | First 5 Authors: Tri Nguyen, Siddharth Mishra-Sharma, Reuel Williams, Lina Necib, | Summary: Dwarf galaxies are small, dark matter-dominated galaxies, some of which are embedded within the Milky Way. Their lack of baryonic matter (e.g., stars and gas) makes them perfect test beds for probing the properties of dark matter […]

Variability Catalog of Stars Observed During the TESS Prime Mission

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Tara Fetherolf, Joshua Pepper, Emilie Simpson, Stephen R. Kane, Teo Mocnik | Summary: During its 2-year Prime Mission, TESS observed over 232,000 stars at a 2-min cadence across ~70% of the sky. These data provide a record of photometric variability across a range of astrophysically interesting time […]

TOI-4562 b: A highly eccentric temperate Jupiter analog orbiting a young field star

Kavli Affiliate: Sara Seager | First 5 Authors: Alexis Heitzmann, George Zhou, Samuel N. Quinn, Chelsea X. Huang, Jiayin Dong | Summary: We report the discovery of TOI-4562 b (TIC-349576261), a Jovian planet orbiting a young F7V-type star, younger than the Praesepe/Hyades clusters ($sim$ 300-400 Myr). This planet stands out because of its unusually long […]

Kavli Affiliate: Andrew M. Vanderburg | First 5 Authors: Alexis Heitzmann, George Zhou, Samuel N. Quinn, Chelsea X. Huang, Jiayin Dong | Summary: We report the discovery of TOI-4562 b (TIC-349576261), a Jovian planet orbiting a young F7V-type star, younger than the Praesepe/Hyades clusters (< $700$ Myr). This planet stands out because of its unusually […]

Extending empirical constraints on the SZ-mass scaling relation to higher redshifts via HST weak lensing measurements of nine clusters from the SPT-SZ survey at $zgtrsim1$

Kavli Affiliate: Michael A. McDonald | First 5 Authors: Hannah Zohren, Tim Schrabback, Sebastian Bocquet, Martin Sommer, Fatimah Raihan | Summary: We present a Hubble Space Telescope (HST) weak gravitational lensing study of nine distant and massive galaxy clusters with redshifts $1.0 lesssim z lesssim 1.7$ ($z_mathrm{median} = 1.4$) and Sunyaev Zel’dovich (SZ) detection significance […]
