Euclid Quick Data Release (Q1) Euclid spectroscopy of quasars. 2. Physical properties from spectral fitting
Euclid Collaboration, J. Calhau, G. Calderone +312
A substantial volume of spectroscopic data has become available with the Euclid Data Release (Q1), which represents a unique opportunity to study quasars (QSOs) in the Euclid Deep…
Characterising cosmic birefringence in the presence of galactic foregrounds and instrumental systematic effects
Baptiste Jost, Josquin Errard, Radek Stompor
We study a possibility of constraining isotropic cosmic birefringence with help of cosmic microwave background polarisation data in the presence of polarisation angle miscalibratio…
Foreground Separation and Constraints on Primordial Gravitational Waves with the PICO Space Mission
Ragnhild Aurlien, Mathieu Remazeilles, Sebastian Belkner +13
PICO is a concept for a NASA probe-scale mission aiming to detect or constrain the tensor to scalar ratio , a parameter that quantifies the amplitude of inflationary gravity wav…
A parametrized quasi-normal mode framework for non-Schwarzschild metrics
Nicola Franchini, Sebastian H. Völkel
In this work we comment in more detail on what happens to the parametrized framework first presented by Cardoso et al. when there are departures from the Schwarzschild background m…
Constraining modifications of black hole perturbation potentials near the light ring with quasinormal modes
Sebastian H. Völkel, Nicola Franchini, Enrico Barausse +1
In modified theories of gravity, the potentials appearing in the Schrödinger-like equations that describe perturbations of non-rotating black holes are also modified. In this paper…
Constraints on the Optical Depth to Reionization from Balloon-Borne CMB Measurements
Josquin Errard, Mathieu Remazeilles, Jonathan Aumont +5
We assess the uncertainty with which a balloon-borne experiment, nominally called Tau Surveyor (), can measure the optical depth to reionization with given realistic con…
