Kavli Affiliate: Jeffrey McMahon | First 5 Authors: Maximilian H. Abitbol, David Alonso, Sara M. Simon, Jack Lashner, Kevin T. Crowley | Summary: We quantify the calibration requirements for systematic uncertainties for next-generation ground-based observatories targeting the large-angle $B$-mode polarization of the Cosmic Microwave Background, with a focus on the Simons Observatory (SO). We explore […]

Kavli Affiliate: Michael Gladders | First 5 Authors: Peter R. Williams, Tommaso Treu, Håkon Dahle, Stefano Valenti, Louis Abramson | Summary: We present the first results of a 4.5 year monitoring campaign of the three bright images of multiply imaged $z=2.805$ quasar SDSS J2222+2745 using the Gemini North Multi-Object Spectrograph (GMOS-N) and the Nordic Optical […]

Kavli Affiliate: Donald York | First 5 Authors: Chen Chen, Fred Hamann, Bo Ma, Britt Lundgren, Donald York | Summary: The early stage of massive galaxy evolution often involves outflows driven by a starburst or a central quasar plus cold mode accretion (infall), which adds to the mass build-up in the galaxies. To study the […]

Kavli Affiliate: John E. Carlstrom | First 5 Authors: Dimitrios Psaltis, Lia Medeiros, Pierre Christian, Feryal Ozel, Kazunori Akiyama | Summary: The 2017 Event Horizon Telescope (EHT) observations of the central source in M87 have led to the first measurement of the size of a black-hole shadow. This observation offers a new and clean gravitational […]

Kavli Affiliate: Austin Joyce | First 5 Authors: Lam Hui, Austin Joyce, Riccardo Penco, Luca Santoni, Adam R. Solomon | Summary: We derive the quadratic action for the physical degrees of freedom of massless spin-0, spin-1, and spin-2 perturbations on a Schwarzschild–(A)dS background in arbitrary dimensions. We then use these results to compute the static […]

Kavli Affiliate: Erik Shirokoff | First 5 Authors: Joaquin Vieira, James Aguirre, C. Matt Bradford, Jeffrey Filippini, Christopher Groppi | Summary: Understanding the formation and evolution of galaxies over cosmic time is one of the foremost goals of astrophysics and cosmology today. The cosmic star formation rate has undergone a dramatic evolution over the course […]

Kavli Affiliate: Michael D. Gladders | First 5 Authors: J. R. Rigby, Michael Florian, A. Acharyya, Matthew Bayliss, Michael D. Gladders | Summary: For the extremely bright lensed galaxy SDSS J1723+3411 at z=1.3293 , we analyze spatially integrated MMT, Keck, and Hubble Space Telescope spectra that fully cover the rest-frame wavelength range of 1400 to […]

Kavli Affiliate: Carlos E. M. Wagner | First 5 Authors: Sebastian Baum, Marcela Carena, Nausheen R. Shah, Carlos E. M. Wagner, Yikun Wang | Summary: Electroweak baryogenesis is an attractive mechanism to generate the baryon asymmetry of the Universe via a strong first order electroweak phase transition. We compare the phase transition patterns suggested by […]

Kavli Affiliate: Michael Turner | First 5 Authors: Gianmarco Mengaldo, David Moxey, Michael Turner, Rodrigo C. Moura, Ayad Jassim | Summary: We present a successful deployment of high-fidelity Large-Eddy Simulation (LES) technologies based on spectral/hp element methods to industrial flow problems, which are characterized by high Reynolds numbers and complex geometries. In particular, we describe […]
