Kavli Affiliate: Martin Haehnelt | First 5 Authors: Joakim Rosdahl, Jérémy Blaizot, Harley Katz, Taysun Kimm, Thibault Garel | Summary: We measure escape fractions, $f_{rm esc}$, of ionizing radiation from galaxies in the SPHINX suite of cosmological radiation-hydrodynamical simulations of reionization, resolving halos with $M_{rm vir} gtrapprox 7.5 times 10^7 M_{odot}$ with a minimum cell […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Alexandra Amon, George Efstathiou, , , | Summary: Weak galaxy lensing surveys have consistently reported a lower amplitude for the matter fluctuation spectrum, as measured by the $S_8$ parameter, than expected in the $Lambda{rm CDM}$ cosmology favoured by $Planck$. However, the expansion history follows the predictions of […]
Kavli Affiliate: Debora Sijacki | First 5 Authors: Sophie Koudmani, Debora Sijacki, Matthew C. Smith, , | Summary: There is growing observational evidence for dwarf galaxies hosting active galactic nuclei (AGN), including hints of AGN-driven outflows in dwarfs. However, in the common theoretical model of galaxy formation, efficient supernova (SN) feedback is the tool of […]

Kavli Affiliate: Anthony Lasenby | First 5 Authors: Michael Hobson, Anthony Lasenby, , , | Summary: For conformally invariant gravity theories defined on Riemannian spacetime and having the Schwarzschild–de-Sitter (SdS) metric as a solution in the Einstein gauge, we consider whether one may conformally rescale this solution to obtain flat rotation curves, such as those […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Adam Marshall, Matthew W. Auger-Williams, Manda Banerji, Roberto Maiolino, Rebecca Bowler | Summary: We perform spectral energy distribution (SED) fitting to 711 luminous X-ray AGN at 0.7 < z < 4.5 using 10-bands of optical and infra-red photometric data for objects within XMM-SERVS. This fitting provided 510 […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Vladan Markov, Stefano Carniani, Livia Vallini, Andrea Ferrara, Andrea Pallottini | Summary: A tight relation between [C II] $ 158 {rm{mu m}}$ line luminosity and star formation rate (SFR) is observed in local galaxies. At $z > 5$, galaxies instead deviate downwards from the local $Sigma_{rm{[C II]}}-Sigma_{rm{SFR}}$ […]

At high redshift (z > 5), galaxies instead deviate downwards from the local $Sigma$_[C II] […]
Kavli Affiliate: Anthony Lasenby | First 5 Authors: Greg Ashton, Noam Bernstein, Johannes Buchner, Xi Chen, Gábor Csányi | Summary: We review Skilling’s nested sampling (NS) algorithm for Bayesian inference and more broadly multi-dimensional integration. After recapitulating the principles of NS, we survey developments in implementing efficient NS algorithms in practice in high-dimensions, including methods […]
