Kavli Affiliate: Wendy Freedman | First 5 Authors: Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu, Yacine Ali-Haimoud, Luca Amendola | Summary: The standard $Lambda$ Cold Dark Matter cosmological model provides an amazing description of a wide range of astrophysical and astronomical data. However, there are a few big open questions, that make the standard […]
Kavli Affiliate: Emil J. Martinec | First 5 Authors: Jeffrey A. Harvey, Emil J. Martinec, Rafael I. Nepomechie, , | Summary: This is a preface to A Passion for Theoretical Physics, a special issue collection of articles published in J. Phys. A in memory of Peter G. O. Freund. | Search Query: ArXiv Query: search_query=au:”Emil […]
Kavli Affiliate: Edward W. Kolb | First 5 Authors: Daniel Carney, Gordan Krnjaic, David C. Moore, Cindy A. Regal, Gadi Afek | Summary: Numerous astrophysical and cosmological observations are best explained by the existence of dark matter, a mass density which interacts only very weakly with visible, baryonic matter. Searching for the extremely weak signals […]
Kavli Affiliate: Jonathan L. Rosner | First 5 Authors: Marek Karliner, Jonathan L. Rosner, , , | Summary: The LHCb Collaboration has reported resonant activity in the channel $D^+ K^-$, identifying two components: $X_0(2900)$ with $J^P = 0^+$ at $2866 {pm} 7$ MeV, $Gamma_0=57{pm} 13$ MeV and $X_1(2900)$ with $J^P = 1^-$ at $2904 {pm} […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: Mohammad Akhshik, Katherine E. Whitaker, Gabriel Brammer, Guillaume Mahler, Keren Sharon | Summary: We present a novel Bayesian methodology to jointly model photometry and deep Hubble Space Telescope (HST) 2d grism spectroscopy of high-redshift galaxies. Our requiem2d code measures both unresolved and resolved stellar populations, ages, […]
Kavli Affiliate: Abigail Vieregg | First 5 Authors: Daniel Smith, Dan Hooper, Abigail Vieregg, , | Summary: The origin of the astrophysical neutrino flux reported by the IceCube Collaboration remains an open question. In this study, we use three years of publicly available IceCube data to search for evidence of neutrino emission from the blazars […]
Kavli Affiliate: Joshua Frieman | First 5 Authors: Qian Yang, Yue Shen, Xin Liu, Michel Aguena, James Annis | Summary: The size of the dust torus in Active Galactic Nuclei (AGN) and their high-luminosity counterparts, quasars, can be inferred from the time delay between UV/optical accretion disk continuum variability and the response in the mid-infrared […]
Kavli Affiliate: Andrey V. Kravtsov | First 5 Authors: Clarke J. Esmerian, Andrey V. Kravtsov, Zachary Hafen, Claude-Andre Faucher-Giguere, Eliot Quataert | Summary: We examine the thermodynamic state and cooling of the low-$z$ Circum-Galactic Medium (CGM) in five FIRE-2 galaxy formation simulations of Milky Way-mass galaxies. We find that the CGM in these simulations is […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: Michael K. Florian, Jane R. Rigby, Ayan Acharyya, Keren Sharon, Michael D. Gladders | Summary: For studies of galaxy formation and evolution, one of the major benefits of the James Webb Space Telescope is that space-based IFUs like those on its NIRSpec and MIRI instruments will […]
Kavli Affiliate: Lindsey E. Bleem | First 5 Authors: Adam B. Mantz, Steven W. Allen, R. Glenn Morris, Rebecca E. A. Canning, Matthew Bayliss | Summary: We present results from a 577 ks XMM-Newton observation of SPT-CL J0459-4947, the most distant cluster detected in the South Pole Telescope 2500 square degree (SPT-SZ) survey, and currently […]
