HierArchical Wavelet Coefficients on the Sphere (HAWCS): the Scattering Transform on Spherical Maps
Arefe Abghari, Lukas T. Hergt, Douglas Scott +1
Extracting Gaussian information from data is well understood, but characterizing non-Gaussianity is challenging. We introduce HAWCS, a healpy-based Python package for efficiently c…
Euclid Quick Data Release (Q1). Searching for radio-selected \Euclid-dark galaxies in the EDF-N
Euclid Collaboration, M. Giulietti, I. Prandoni +308
We present and investigate the properties of a sample of radio-selected, Euclid-dark galaxies, identified from LOFAR HBA observations at 144 MHz within the Euclid Deep Field-North…
Euclid Quick Data Release (Q1). The average far-infrared properties of Euclid-selected star-forming galaxies
Euclid Collaboration, R. Hill, A. Abghari +302
The first Euclid Quick Data Release contains millions of galaxies with excellent optical and near-infrared (IR) coverage. To complement this dataset, we investigate the average far…
Planck PR4 (NPIPE) map-space cosmic birefringence
Raelyn Marguerite Sullivan, Arefe Abghari, Patricia Diego-Palazuelos +2
Cosmic birefringence is an effect where the plane of polarisation of the cosmic microwave background (CMB) is rotated by an angle through coupling to a hypothetical parity-viol…
Reassessment of the dipole in the distribution of quasars on the sky
Arefe Abghari, Emory F. Bunn, Lukas T. Hergt +4
We investigate recent claims by Secrest et al. of an anomalously large amplitude of the dipole in the distribution of CatWISE-selected quasars on the sky. Two main issues indicate…
Constraints on cosmic birefringence using -mode polarisation
Arefe Abghari, Raelyn M. Sullivan, Lukas T. Hergt +1
A birefringent universe could show itself through a rotation of the plane of polarisation of the cosmic microwave background photons. This is usually investigated using polarisatio…
