FEASTS Combined with Interferometry. III. The Low-column-density HI Around M51 and Possibility of Turbulent-mixing Gas Accretion

Kavli Affiliate: Luis C. Ho | First 5 Authors: Xuchen Lin, Jing Wang, Lister Staveley-Smith, Suoqing Ji, Dong Yang | Summary: With a new joint-deconvolution pipeline, we combine the single-dish and interferometric atomic hydrogen (HI) data of M51 observed by the FAST (FEASTS program) and VLA (THINGS). The product data cube has a typical line […]

The Power Spectrum of the Thermal Sunyaev-Zeldovich Effect

Kavli Affiliate: George Efstathiou | First 5 Authors: George Efstathiou, Fiona McCarthy, , , | Summary: The power spectrum of unresolved thermal Sunyaev-Zeldovich (tSZ) clusters is extremely sensitive to the amplitude of the matter fluctuations. This paper present an analysis of the tSZ power spectrum using temperature power spectra of the cosmic microwave background (CMB) […]

Evidence of the P_ccbars(4459)0 in Upsilon(1S, 2S) inclusive decays at Belle

Kavli Affiliate: T. Higuchi | First 5 Authors: I. Adachi, L. Aggarwal, H. Ahmed, J. K. Ahn, H. Aihara | Summary: Using data samples of 102 million Upsilon(1S) events and 158 million Upsilon(2S) events collected by the Belle detector at the KEKB asymmetric-energy e+e- collider, we search for [udsccbar] pentaquark states decaying to Jpsi Lambda. […]

$Λ$CDM and early dark energy in latent space: a data-driven parametrization of the CMB temperature power spectrum

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Davide Piras, Laura Herold, Luisa Lucie-Smith, Eiichiro Komatsu, | Summary: Finding the best parametrization for cosmological models in the absence of first-principle theories is an open question. We propose a data-driven parametrization of cosmological models given by the disentangled ‘latent’ representation of a variational autoencoder (VAE) trained […]

The Pristine survey: XXVIII. The extremely metal-poor stream C-19 stretches over more than 100 degrees

Zhen Yuan, Tadafumi Matsuno, Tatyana Sitnova, Nicolas F. Martin, Rodrigo A. Ibata | Summary: [[{“value”:”The discovery of the most metal-poor stream, C-19, provides us with a fossil record of a stellar structure born very soon after the Big Bang. In this work, we search for new C-19 members over the whole sky by combining two […]

Searching for axion dark matter gegenschein of the Vela supernova remnant with FAST

Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Wenxiu Yang, Yitian Sun, Yougang Wang, Katelin Schutz, Yichao Li | Summary: Axions are one of the leading dark matter candidates. If we are embedded in a Milky Way dark matter halo comprised of axions, their stimulated decay would enable us to observe a counterimage (“axion gegenschein") […]
