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 […]

Variational Tensor Wavefunctions for the Interacting Quantum Spin Hall Phase

Posted by klaurent UCAS

Kavli Affiliate: Shenghan Jiang | First 5 Authors: Yixin Ma, Shenghan Jiang, Chao Xu, , | Summary: The quantum spin hall (QSH) phase, also known as the two-dimensional topological insulator, hosts helical edge modes protected by time-reversal symmetry. While first proposed as a band insulator, this phase can also be realized in strongly-correlated systems, where […]

$g$-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 […]

Rydberg Excitons and Trions in Monolayer MoTe$_2$

Posted by klaurent Caltech

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Souvik Biswas, Aurélie Champagne, Jonah B. Haber, Supavit Pokawanvit, Joeson Wong | Summary: Monolayer transition metal dichalcogenide (TMDC) semiconductors exhibit strong excitonic optical resonances which serve as a microscopic, non-invasive probe into their fundamental properties. Like the hydrogen atom, such excitons can exhibit an entire Rydberg […]
