Derived categories of Quot schemes of locally free quotients via categorified Hall products

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Yukinobu Toda, , , , | Summary: We prove Qingyuan Jiang’s conjecture on semiorthogonal decompositions of derived categories of Quot schemes of locally free quotients. The author’s result on categorified Hall products for Grassmannian flips is applied to prove the conjecture. | Search Query: ArXiv Query: search_query=au:”Yukinobu […]

The High Latitude Spectroscopic Survey on the Nancy Grace Roman Space Telescope

Kavli Affiliate: David Spergel | First 5 Authors: Yun Wang, Zhongxu Zhai, Anahita Alavi, Elena Massara, Alice Pisani | Summary: The Nancy Grace Roman Space Telescope will conduct a High Latitude Spectroscopic Survey (HLSS) over a large volume at high redshift, using the near-IR grism (1.0-1.93 $mu$m, $R=435-865$) and the 0.28 deg$^2$ wide field camera. […]

Cosmological constraints without fingers of God

Kavli Affiliate: Masahiro Takada | First 5 Authors: Mikhail M. Ivanov, Oliver H. E. Philcox, Marko Simonović, Matias Zaldarriaga, Takahiro Nishimichi | Summary: Non-linear redshift-space distortions ("fingers of God") are challenging to model analytically, a fact that limits the applicability of perturbation theory in redshift space as compared to real space. We show how this […]

A Large Diameter Millimeter-Wave Low-Pass Filter Made of Alumina with Laser Ablated Anti-Reflection Coating

Kavli Affiliate: Nobuhiko Katayama | First 5 Authors: Ryota Takaku, Qi Wen, Scott Cray, Mark Devlin, Simon Dicker | Summary: We fabricated a 302 mm diameter low-pass filter made of alumina that has an anti-reflection coating (ARC) made with laser-ablated sub-wavelength structures (SWS). The filter has been integrated into and is operating with the MUSTANG2 […]

Bounded multiplicity theorems for induction and restriction

Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Toshiyuki Kobayashi, , , , | Summary: We prove a geometric criterion for the bounded multiplicity property of "small" infinite-dimensional representations of real reductive Lie groupsin both induction and restrictions. Applying the criterion to symmetric pairs, we give a full description of the triples $H subset G […]

Primordial Black Holes from CDM Isocurvature

Kavli Affiliate: Misao Sasaki | First 5 Authors: Samuel Passaglia, Misao Sasaki, , , | Summary: We show that primordial black holes can be produced from the collapse of large isocurvature perturbations of the cold dark matter. We develop a novel procedure to compute the resulting black hole abundance by studying matched perturbations of matter-only […]
