Small Region, Big Impact: Highly Anisotropic Lyman-continuum Escape from a Compact Starburst Region with Extreme Physical Properties

Posted by Chicago

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Keunho J. Kim, Matthew B. Bayliss, Jane R. Rigby, Michael D. Gladders, John Chisholm | Summary: Extreme, young stellar populations are considered the primary contributor to cosmic reionization. However, how Lyman-continuum (LyC) escapes these galaxies remains highly elusive because LyC escape can vary on sub-galactic scales […]

Continuous Wigner-Mott transition at $ν=1/5$

Posted by Cornell

Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Thomas G. Kiely, Debanjan Chowdhury, , , | Summary: Electrons can organize themselves into charge-ordered states to minimize the effects of long-ranged Coulomb interactions. In the presence of a lattice, commensurability constraints lead to the emergence of incompressible Wigner-Mott insulators at various rational electron fillings, $nu~=p/q$. The […]

Measuring $μ$-Distortions from the Thermal Sunyaev-Zeldovich effect

Posted by Chicago

Kavli Affiliate: Wayne Hu | First 5 Authors: David Zegeye, Thomas Crawford, Wayne Hu, , | Summary: The thermal Sunyaev-Zel’dovich (tSZ) effect is a spectral distortion of the cosmic microwave background (CMB) resulting from inverse Compton scattering of CMB photons with electrons in the medium of galaxy clusters. The spectrum of the tSZ effect is […]

Visible to Ultraviolet Frequency Comb Generation in Lithium Niobate Nanophotonic Waveguides

Posted by Caltech

Kavli Affiliate: Alireza Marandi | First 5 Authors: Tsung-Han Wu, Luis Ledezma, Connor Fredrick, Pooja Sekhar, Ryoto Sekine | Summary: The introduction of nonlinear nanophotonic devices to the field of optical frequency comb metrology has enabled new opportunities for low-power and chip-integrated clocks, high-precision frequency synthesis, and broad bandwidth spectroscopy. However, most of these advances […]

Quantifying Uncertainties on the Tip of the Red Giant Branch Method

Posted by Chicago

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Barry F. Madore, Wendy L. Freedman Kayla A. Owens, In Sung Jang, , | Summary: We present an extensive grid of numerical simulations quantifying the uncertainties in measurements of the Tip of the Red Giant Branch (TRGB). These simulations incorporate a luminosity function composed of 2 […]

A quantitative comparison between velocity dependent SIDM cross sections constrained by the gravothermal and isothermal models

Posted by Peking

Shengqi Yang, Fangzhou Jiang, Andrew Benson, Yi-Ming Zhong, Charlie Mace | Summary: [[{“value”:”One necessary step for probing the nature of self-interacting dark matter (SIDM) particles with astrophysical observations is to pin down any possible velocity dependence in the SIDM cross section. Major challenges for achieving this goal include eliminating, or mitigating, the impact of the […]

SENSEI: Search for Millicharged Particles produced in the NuMI Beam

Posted by Chicago

Kavli Affiliate: Michael Crisler | First 5 Authors: Liron Barak, Itay M. Bloch, Ana M. Botti, Mariano Cababie, Gustavo Cancelo | Summary: Millicharged particles appear in several extensions of the Standard Model, but have not yet been detected. These hypothetical particles could be produced by an intense proton beam striking a fixed target. We use […]
