In particular, precision measurements of its polarization can reveal the existence of gravitational waves produced during cosmic inflation. However, these observations are complicated by the presence of astrophysical foregrounds, which may be separated by using broad frequency coverage, as the spectral energy distribution between foregrounds and the CMB is distinct. For this purpose, we are developing large-bandwidth, feedhorn-coupled transition-edge-sensor (TES) arrays. In this work, we describe two types of pixels, an ultra-high frequency (UHF) design, which operates from 195 GHz-315 GHz, and an extended ultra-high frequency (UHF++) design, which operates from 195 GHz-420 GHz, being developed for next generation CMB experiments that will come online in the next decade, in particular, CCAT-prime and the Simons Observatory. We present the designs, simulation results, and preliminary measurements of these prototype pixels. Cheers, Martina -------------- next part -------------- An HTML attachment was scrubbed...

Natalia Porqueres from the Max Planck Institute for Astrophysics in Munich will give a seminar on the following topic: Title: Inferring high-redshift large-scale structure dynamics from the Lyman-alpha forest Abstract: Galaxy redshift surveys allow probing the cosmic large-scale structure of the Universe with high accuracy. Their statistical analyses have provided precise measurements of the cosmological parameters and the matter power spectrum. However, galaxy surveys are limited in redshift. How can the study of the large-scale structure be extended to the high-redshift Universe? The Lyman-alpha forest in the quasar spectra provides an alternative probe of the large-scale structure that allows us to go beyond the redshift of galaxy surveys (z > 2). We present a Bayesian framework to infer the three-dimensional large-scale density field and its dynamics at high-redshift from the Lyman-α forest. Our analysis allows the exploration of the initial conditions by evolving the density field to z = 2.5 with a physical model, in this case, Lagrangian perturbation theory. This dynamical model allows to naturally infer the velocity field, providing possible formation histories and revealing the large-scale dynamics at high-redshift. We tested and validated our method with mock Ly-α data from the COSMOS Lyman-Alpha Mapping And Tomography Observations (CLAMATO) survey, showing that our method accurately recovers the underlying density field and allows the study of the cosmic web at high-redshift.

Steffen Hagstotz from the Department of Physics, SU will give a seminar on the following topic: Title: Hunting Modified Gravity and Neutrinos with Clusters of Galaxies Abstract: Considerable effort in cosmology is focused on understanding the statistical nature of the cosmological density field that underlies the observable large-scale structure. Clusters of galaxies trace the highest, non-Gaussian peaks of the matter density, and their abundance is a sensitive probe of both underlying cosmological parameters as well as of the physics governing structure formation. In my talk I will explain how cluster abundance can be used to search for modifications of gravity via the impact on spherical collapse and why neutrinos are a crucial component in these searches. In addition, astrophysical signatures within the cluster can be a key signal themselves and I will demonstrate how to incorporate them consistently in searches to constrain deviations from general relativity.

Date: November 7, Wednesday Time: 13:15 Place: C6: 1038 Christiane Lorenz from the Department of Physics, University of Oxford will give a seminar. Christiane is supervised by Pedro Ferreira, Erminia Calabrese and David Alonso. Her main aim is to test neutrino models with cosmological observations, for example with observations of the cosmic microwave background and of the large scale structure of the Universe. Title: Robust neutrino mass measurements in cosmology Abstract: In this talk, I will present studies of the model-dependence of cosmological neutrino mass constraints. In particular, I will focus on two phenomenological parameterizations of time-varying dark energy (early dark energy and barotropic dark energy) that can exhibit degeneracies with the cosmic neutrino background over extended periods of cosmic time. Moreover, I will show how the combination of multiple probes across cosmic time can help to distinguish between the two components. In addition, I will discuss how neutrino mass constraints can change in extended neutrino mass models, and how current tensions between low- and high-redshift cosmological data might be affected in these models.
