Repeating nuclear transients from repeating partial tidal disruption events: reproducing ASASSN-14ko and AT2020vdq

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Ananya Bandopadhyay, Eric R. Coughlin, C. J. Nixon, Dheeraj R. Pasham, | Summary: Some electromagnetic outbursts from the nuclei of distant galaxies have been found to repeat on months-to-years timescales, and each of these sources can putatively arise from the accretion flares generated through the repeated […]

Gravitational-wave data analysis with high-precision numerical relativity simulations of boson star mergers

Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Tamara Evstafyeva, Ulrich Sperhake, Isobel Romero-Shaw, Michalis Agathos, | Summary: Gravitational-wave signals detected to date are commonly interpreted under the paradigm that they originate from pairs of black holes or neutron stars. Here, we explore the alternative scenario of boson-star signals being present in the data stream. […]

The R-Process Alliance: 2MASS J22132050-5137385, the Star with the Highest-known r-process Enhancement at [Eu/Fe] = +2.45

Kavli Affiliate: Anna Frebel | First 5 Authors: Ian U. Roederer, Timothy C. Beers, Kohei Hattori, Vinicius M. Placco, Terese T. Hansen | Summary: We present stellar parameters and chemical abundances of 47 elements detected in the bright (V = 11.63) very metal-poor ([Fe/H] = -2.20 +- 0.12) star 2MASS J22132050-5137385. We observed this star […]

TDCOSMO. XVII. Measurement of the Hubble Constant from the Lensed Quasar WGD$,$2038$-$4008

Kavli Affiliate: Philip J. Marshall | First 5 Authors: Kenneth C. Wong, Frédéric Dux, Anowar J. Shajib, Sherry H. Suyu, Martin Millon | Summary: Time-delay cosmography is a powerful technique to constrain cosmological parameters, particularly the Hubble constant ($H_{0}$). The TDCOSMO collaboration is performing an ongoing analysis of lensed quasars to constrain cosmology using this […]

The MAGPI Survey: Massive slow rotator population in place by $z sim 0.3$

Kavli Affiliate: Yingjie Peng | First 5 Authors: Caro Derkenne, Richard M. McDermid, Francesco D’Eugenio, Caroline Foster, Aman Khalid | Summary: We use the `Middle Ages Galaxy Properties with Integral field spectroscopy’ (MAGPI) survey to investigate whether galaxies have evolved in the distribution of their stellar angular momentum in the past 3-4 Gyr, as probed […]

Fermion-fermion interaction driven phase transitions in the rhombohedral trilayer graphene

Kavli Affiliate: Jing Wang | First 5 Authors: Qiao-Chu Zhang, Jing Wang, , , | Summary: The effects of short-range fermion-fermion interactions on the low-energy properties of the rhombohedral trilayer graphene are comprehensively investigated by virtue of the momentum-shell renormalization group method. We take into account all one-loop corrections and establish the energy-dependent coupled evolutions […]
