Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Roxana Rosca-Mead, Ulrich Sperhake, Christopher J. Moore, Michalis Agathos, Davide Gerosa | Summary: This paper provides an extended exploration of the inverse-chirp gravitational-wave signals from stellar collapse in massive scalar-tensor gravity reported in [Phys. Rev. Lett. {bf 119}, 201103]. We systematically explore the parameter space that characterizes […]
Kavli Affiliate: Anthony Lasenby | First 5 Authors: Kamran Javid, Will Handley, Mike Hobson, Anthony Lasenby, | Summary: We conduct a thorough analysis of the relationship between the out-of-sample performance and the Bayesian evidence (marginal likelihood) of Bayesian neural networks (BNNs), as well as looking at the performance of ensembles of BNNs, both using the […]
Kavli Affiliate: Anthony Challinor | First 5 Authors: Anirban Roy, Girish Kulkarni, P. Daniel Meerburg, Anthony Challinor, Carlo Baccigalupi | Summary: The search for primordial gravitational waves through the $B$-mode polarization pattern in the CMB is one of the major goals of current and future CMB experiments. Besides foregrounds, a potential hurdle in this search […]
Kavli Affiliate: George Efstathiou | First 5 Authors: George Efstathiou, Steven Gratton, , , | Summary: We revisit the observational constraints on spatial curvature following recent claims that the Planck data favour a closed Universe. We use a new and statistically powerful Planck likelihood to show that the Planck temperature and polarization spectra are consistent […]
Kavli Affiliate: R. G. McMahon | First 5 Authors: Estelle Pons, Richard G. McMahon, Manda Banerji, Sophie L. Reed, | Summary: We present XMM-Newton X-ray observations and analysis of three DES $z>6.5$ quasars (VDES J0020$-$3653 at $z=6.824$, VDES J0244$-$5008 at $z=6.724$ and VDES J0224$-$4711 at $z=6.526$) and six other quasars with $6.438 < z < […]
Kavli Affiliate: R. G. McMahon | First 5 Authors: Yiping Shu, Sergey E. Koposov, N. Wyn Evans, Vasily Belokurov, Richard G. McMahon | Summary: We present two catalogues of active galactic nucleus (AGN) candidates selected from the latest data of two all-sky surveys — Data Release 2 (DR2) of the emph{Gaia} mission and the unWISE […]
Kavli Affiliate: A. C. Davis | First 5 Authors: Y. Ali-Haimoud, S. Clesse, J. Garcia-Bellido, A. Kashlinsky, L. Wyrzykowski | Summary: The LIGO discoveries have rekindled suggestions that primordial black holes (BHs) may constitute part to all of the dark matter (DM) in the Universe. Such suggestions came from 1) the observed merger rate of […]
Kavli Affiliate: Richard Hills | First 5 Authors: Richard Hills, Girish Kulkarni, P. Daniel Meerburg, Ewald Puchwein, | Summary: It is predicted that the spectrum of radio emission from the whole sky should show a dip arising from the action of the light from the first stars on the hydrogen atoms in the surrounding gas, […]
Kavli Affiliate: R. G. McMahon | First 5 Authors: Bram Venemans, Fabian Walter, Roberto Decarli, Carl Ferkinhoff, Axel Weiss | Summary: We present ALMA band 3 observations of the CO(6-5), CO(7-6), and [CI] 369micron emission lines in three of the highest redshift quasar host galaxies at 6.6<z<6.9. These measurements constitute the highest-redshift CO detections to […]
Kavli Affiliate: R. G. McMahon | First 5 Authors: Bram Venemans, Fabian Walter, Roberto Decarli, Eduardo Banados, Jacqueline Hodge | Summary: We present ALMA observations of the [CII] fine structure line and the underlying far-infrared (FIR) dust continuum emission in J1120+0641, the most distant quasar currently known (z=7.1). We also present observations targeting the CO(2-1), […]
