PROBs and perverse sheaves II. Ran spaces and 0-cycles with coefficients

Kavli Affiliate: Mikhail Kapranov | First 5 Authors: Mikhail Kapranov, Vadim Schechtman, , , | Summary: We consider the space Z(C,L) of 0-cycles on the complex line C with coefficients in a commutative monoid L subject to certain conditions. Such spaces include the symmetric products (for L=Z_+) and the Ran space (for L=T={ True, False} […]

Scale-invariant enhancement of gravitational waves during inflation

Kavli Affiliate: Misao Sasaki | First 5 Authors: Atsuhisa Ota, Misao Sasaki, Yi Wang, , | Summary: The inflationary 1-loop tensor power spectrum from an excited spectator scalar field is calculated. Recent studies on primordial black holes suggest that the inflationary curvature perturbation may be huge on small scales. An enhanced curvature perturbation may arise […]

The SZ flux-mass ($Y$-$M$) relation at low halo masses: improvements with symbolic regression and strong constraints on baryonic feedback

Kavli Affiliate: David N. Spergel | First 5 Authors: Digvijay Wadekar, Leander Thiele, J. Colin Hill, Shivam Pandey, Francisco Villaescusa-Navarro | Summary: Ionized gas in the halo circumgalactic medium leaves an imprint on the cosmic microwave background via the thermal Sunyaev-Zeldovich (tSZ) effect. Feedback from active galactic nuclei (AGN) and supernovae can affect the measurements […]

The SZ flux-mass ($Y$-$M$) relation at low halo masses: improvements with symbolic regression and strong constraints on baryonic feedback

Kavli Affiliate: David N. Spergel | First 5 Authors: Digvijay Wadekar, Leander Thiele, J. Colin Hill, Shivam Pandey, Francisco Villaescusa-Navarro | Summary: Feedback from active galactic nuclei (AGN) and supernovae can affect measurements of integrated SZ flux of halos ($Y_mathrm{SZ}$) from CMB surveys, and cause its relation with the halo mass ($Y_mathrm{SZ}-M$) to deviate from […]

Observation of $e^+e^-toωχ_{bJ}(1P)$ and search for $X_b to ωΥ(1S)$ at $sqrt{s}$ near 10.75 GeV

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II collaboration, I. Adachi, L. Aggarwal, H. Ahmed, H. Aihara | Summary: We study the processes $e^+e^-toomegachi_{bJ}(1P)$ ($J$ = 0, 1, or 2) using samples at center-of-mass energies $sqrt{s}$ = 10.701, 10.745, and 10.805 GeV, corresponding to 1.6, 9.8, and 4.7 fb$^{-1}$ of integrated luminosity, respectively.

On the formation of over-ionized plasma in evolved supernova remnants

Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Miho Katsuragawa, Shiu-Hang Lee, Hirokazu Odaka, Aya Bamba, Hideaki Matsumura | Summary: One of the outstanding mysteries surrounding the rich diversity found in supernova remnants (SNRs) is the recent discovery of over-ionized or recombining plasma from a number of dynamically evolved objects. To help decipher its formation […]

A comparison between compactly supported rigid and $pmb{mathscr{D}}$-module cohomology

Kavli Affiliate: Tomoyuki Abe | First 5 Authors: Tomoyuki Abe, Christopher Lazda, , , | Summary: The goal of this article is to prove a comparison theorem between rigid cohomology and cohomology computed using the theory of arithmetic $mathscr{D}$-modules. To do this, we construct a specialisation functor from Le Stum’s category of constructible isocrystals to […]
