Searching for Gravitational-Wave Counterparts using the Transiting Exoplanet Survey Satellite

Posted by klaurent MIT

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Geoffrey Mo, Rahul Jayaraman, Michael Fausnaugh, Erik Katsavounidis, George R. Ricker | Summary: In 2017, the LIGO and Virgo gravitational wave (GW) detectors, in conjunction with electromagnetic (EM) astronomers, observed the first GW multi-messenger astrophysical event, the binary neutron star (BNS) merger GW170817. This marked the beginning […]

GA-NIFS: Black hole and host galaxy properties of two z$simeq$6.8 quasars from the NIRSpec IFU

Posted by klaurent Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Madeline A. Marshall, Michele Perna, Chris J. Willott, Roberto Maiolino, Jan Scholtz | Summary: Integral Field Spectroscopy (IFS) with JWST NIRSpec will significantly improve our understanding of the first quasars, by providing spatially resolved, infrared spectroscopic capabilities which cover key rest-frame optical emission lines that have been […]

Reconstruction of a surface from the category of reflexive sheaves

Posted by klaurent Tokyo

Kavli Affiliate: Alexey Bondal | First 5 Authors: Agnieszka Bodzenta, Alexey Bondal, , , | Summary: We define a normal surface $X$ to be codim-2-saturated if any open embedding of $X$ into a normal surface with the complement of codimension 2 is an isomorphism. We show that any normal surface $X$ allows a codim-2-saturated model […]

JADES: Probing interstellar medium conditions at $zsim5.5-9.5$ with ultra-deep JWST/NIRSpec spectroscopy

Posted by klaurent Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Alex J. Cameron, Aayush Saxena, Andrew J. Bunker, Francesco D’Eugenio, Stefano Carniani | Summary: We present emission line ratios from a sample of 26 Lyman break galaxies from $zsim5.5-9.5$ with $-17.0<M_{1500}<-20.4$, measured from ultra-deep JWST/NIRSpec MSA spectroscopy from JADES. We use 28 hour deep PRISM/CLEAR and 7 […]

Modeling the Galaxy Distribution in Clusters using Halo Cores

Posted by Chicago

Kavli Affiliate: Salman Habib | First 5 Authors: Danila Korytov, Esteban Rangel, Lindsey Bleem, Nicholas Frontiere, Salman Habib | Summary: The galaxy distribution in dark matter-dominated halos is expected to approximately trace the details of the underlying dark matter substructure. In this paper we introduce halo `core-tracking’ as a way to efficiently follow the small-scale […]

$g$-mode of neutron stars in pseudo-Newtonian gravity

Posted by klaurent Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Hong-Bo Li, Yong Gao, Lijing Shao, Renxin Xu, | Summary: The equation of state (EOS) of nuclear dense matter plays a crucial role in many astrophysical phenomena associated with neutron stars (NSs). Fluid oscillations are one of the most fundamental properties therein. NSs support a family of […]
