Target of Opportunity Observations of Gravitational Wave Events with Vera C. Rubin Observatory

Posted by klaurent Chicago

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Igor Andreoni, Raffaella Margutti, Om Sharan Salafia, B. Parazin, V. Ashley Villar | Summary: The discovery of the electromagnetic counterpart to the binary neutron star merger GW170817 has opened the era of gravitational-wave multi-messenger astronomy. Rapid identification of the optical/infrared kilonova enabled a precise localization of […]

Testing solar surface flux transport models in the first days after active region emergence

Posted by klaurent Stanford

Kavli Affiliate: Robert Cameron | First 5 Authors: Nils Gottschling, Hannah Schunker, Aaron C. Birch, Robert Cameron, Laurent Gizon | Summary: Active regions (ARs) play an important role in the magnetic dynamics of the Sun. Solar surface flux transport models (SFTMs) are used to describe the evolution of the radial magnetic field at the solar […]

Blandford-Znajek jets in galaxy formation simulations: exploring the diversity of outflows produced by spin-driven AGN jets in Seyfert galaxies

Posted by klaurent Cambridge

Kavli Affiliate: Debora Sijacki | First 5 Authors: Rosie Y. Talbot, Debora Sijacki, Martin A. Bourne, , | Summary: Recent observations of Seyfert galaxies indicate that low power, misaligned jets can undergo significant interaction with the gas in the galactic disc and may be able to drive large-scale, multiphase outflows. We apply our novel sub-grid […]

Direct Computation of Monodromy Matrices and Classification of 4d N=2 Heterotic–IIA Dual Vacua

Posted by klaurent Tokyo

Kavli Affiliate: Taizan Watari | First 5 Authors: Yuichi Enoki, Taizan Watari, , , | Summary: We compute the monodromy matrices on the special geometry of 4d N=2 Heterotic–IIA dual vacua in some simple cases by numerical evaluation of the period integrals, without assuming geometric background. The integrality of the monodromy matrices constrains some classification […]

Physics of star formation history and the luminosity function of galaxies therefrom

Posted by klaurent Tokyo

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masataka Fukugita, Masahiro Kawasaki, , , | Summary: We show that the star formation history, the reionization history and the luminosity function of galaxies are successfully predicted in a simple gravitational collapse model within the $Lambda$CDM regime to almost a quantitative accuracy, when the physical conditions, the […]

Discovery of a protocluster core associated with an enormous Ly$α$ Nebula at $z = 2.3$

Posted by klaurent Peking

Kavli Affiliate: Ran Wang | First 5 Authors: Qiong Li, Ran Wang, Helmut Dannerbauer, Zheng Cai, Bjorn Emonts | Summary: The MAMMOTH-1 nebula at $z=2.317$ is an enormous Ly$alpha$ nebula (ELAN) extending to a $sim$440 kpc scale at the center of the extreme galaxy overdensity BOSS 1441. In this paper, we present observations of the […]

The Variability of the Black-Hole Image in M87 at the Dynamical Time Scale

Posted by Chicago

Kavli Affiliate: John E. Carlstrom | First 5 Authors: Kaushik Satapathy, Dimitrios Psaltis, Feryal Ozel, Lia Medeiros, Sean T. Dougall | Summary: The black-hole images obtained with the Event Horizon Telescope (EHT) are expected to be variable at the dynamical timescale near their horizons. For the black hole at the center of the M87 galaxy, […]

TOI-2076 and TOI-1807: Two young, comoving planetary systems within 50 pc identified by TESS that are ideal candidates for further follow-up

Posted by klaurent MIT

Kavli Affiliate: Roland K. Vanderspek | First 5 Authors: Christina Hedges, Alex Hughes, Steven Giacalone, George Zhou, Trevor J. David | Summary: We report the discovery of two planetary systems around comoving stars; TOI-2076 (TIC 27491137) and TOI-1807 (TIC 180695581). TOI-2076 is a nearby (41.9 pc) multi-planetary system orbiting a young (204$pm$50 Myr), bright (K […]
