Exploring the dispersion measure of the Milky Way halo
Laura C. Keating, Ue-Li Pen
Fast radio bursts offer the opportunity to place new constraints on the mass and density profile of hot and ionized gas in galactic haloes. We test here the X-ray emission and disp…
Probing the thermal state of the intergalactic medium at with the transmission spikes in high-resolution Ly forest spectra
Prakash Gaikwad, Michael Rauch, Martin G. Haehnelt +13
We compare a sample of five high-resolution, high S/N Ly forest spectra of bright QSOs aimed at spectrally resolving the last remaining transmission spikes at…
Reproducing the CO-to-H conversion factor in cosmological simulations of Milky Way-mass galaxies
Laura C. Keating, Alexander J. Richings, Norman Murray +8
We present models of CO(1-0) emission from Milky Way-mass galaxies at redshift zero in the FIRE-2 cosmological zoom-in simulations. We calculate the molecular abundances by post-pr…
Constraining the second half of reionization with the Lyman- forest
Laura C. Keating, Girish Kulkarni, Martin G. Haehnelt +2
We present an analysis of the evolution of the Lyman-series forest into the epoch of reionization using cosmological radiative transfer simulations in a scenario where reionization…
The CCAT-Prime Submillimeter Observatory
Manuel Aravena, Jason Austermann, Kaustuv Basu +53
The Cerro Chajnantor Atacama Telescope-prime (CCAT-prime) is a new 6-m, off-axis, low-emissivity, large field-of-view submillimeter telescope scheduled for first light in the last…
Long troughs in the Lyman- forest below redshift 6 due to islands of neutral hydrogen
Laura C. Keating, Lewis H. Weinberger, Girish Kulkarni +3
A long (110 cMpc/) and deep absorption trough in the Ly forest has been observed extending down to redshift 5.5 in the spectrum of ULAS J0148+0600. Although no Ly transmis…
