Modeling the inner part of M87 jet: confronting jet morphology with theory

Kavli Affiliate: Feng Yuan | First 5 Authors: Hai Yang, Feng Yuan, Hui Li, Yosuke Mizuno, Fan Guo | Summary: The formation of jets in black hole accretion systems is a long-standing problem. It has been proposed that a jet can be formed by extracting the rotation energy of the black hole ("BZ-jet") or the […]

The stellar halo in Local Group Hestia simulations III. Chemical abundance relations for accreted and in-situ stars

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Sergey Khoperskov, Ivan Minchev, Noam Libeskind, Vasily Belokurov, Matthias Steinmetz | Summary: Since the chemical abundances of stars are the fossil records of the physical conditions in galaxies, they provide the key information for recovering the assembly history of galaxies. In this work, we explore the chemo-chrono-kinematics […]

Impact of late-time neutrino emission on the Diffuse Supernova Neutrino Background

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Nick Ekanger, Shunsaku Horiuchi, Kei Kotake, Kohsuke Sumiyoshi, | Summary: In the absence of high-statistics supernova neutrino measurements, estimates of the diffuse supernova neutrino background (DSNB) hinge on the precision of simulations of core-collapse supernovae (CCSNe). Understanding the cooling phase of protoneutron star (PNS) evolution ($gtrsim1,{rm s}$ […]

Applications of a perturbation-aware local correlation method to coupled cluster linear response properties

Kavli Affiliate: Thomas Crawford | First 5 Authors: Ruhee D’Cunha, T. Daniel Crawford, , , | Summary: We have investigated the efficacy of two recently proposed variations of the pair-natural-orbital approach to reducing the scaling of coupled cluster property calculations. In particular, we have extended our implementations of the PNO++ and combined PNO++ methods, which […]

Testing the Reliability of X-rays as a Tool for Constraining Mass-loss Rates of Hot Stars

Kavli Affiliate: David P. Huenemoerder | First 5 Authors: Sean J. Gunderson, Kenneth G. Gayley, Pragati Pradhan, David P. Huenemoerder, Nathan A. Miller | Summary: We fit a new line shape model to textit{Chandra} X-ray spectra of the O supergiant $zeta$ Puppis to test the robustness of mass-loss rates derived from X-ray wind line profiles […]

Evolution of a Relativistic Outflow and X-ray Corona in the Extreme Changing-Look AGN 1ES 1927+654

Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Megan Masterson, Erin Kara, Claudio Ricci, Javier A. GarcĂ­a, Andrew C. Fabian | Summary: 1ES 1927+654 is a paradigm-defying AGN and one of the most peculiar X-ray nuclear transients. In early 2018, this well-known AGN underwent a changing-look event, in which broad optical emission lines appeared […]
