Cosmology from Clustering of Continuum Galaxies
Jacobo Asorey, Catherine L. Hale, Sebastian von Hausegger +6
The distribution of radio continuum galaxies is a useful, fast, and accessible probe of the matter distribution in the Universe, enlightening us about the Universe's initial condit…
Testing cosmic anisotropy with cluster scaling relations
Tariq Yasin, Richard Stiskalek, Harry Desmond +2
We test claims of large-scale anisotropy in the local expansion rate using cluster scaling relations as distance indicators. Using a Bayesian forward model, we jointly fit the X-ra…
Colloquium: The Cosmic Dipole Anomaly
Nathan Secrest, Sebastian von Hausegger, Mohamed Rameez +2
The Cosmological Principle, which states that the Universe is homogeneous and isotropic (when averaged on large scales), is the foundational assumption of Friedmann-Lemaitre-Robert…
Forty years of the Ellis-Baldwin test
Nathan Secrest, Sebastian von Hausegger, Mohamed Rameez +2
Modern cosmology is built on the assumption that the Universe is homogeneous and isotropic on large scales - but this is challenged by results of the Ellis-Baldwin test that show a…
Impact of Galactic dust non-Gaussianity on searches for B-modes from inflation
Irene Abril-Cabezas, Carlos Hervías-Caimapo, Sebastian von Hausegger +2
A key challenge in the search for primordial B-modes is the presence of polarized Galactic foregrounds, especially thermal dust emission. Power-spectrum-based analysis methods gene…
B-mode polarization forecasts for GreenPol
U. Fuskeland, A. Kaplan, I. K. Wehus +9
We present tensor-to-scalar ratio forecasts for GreenPol, a hypothetical ground-based B-mode experiment aiming to survey the cleanest regions of the Northern Galactic Hemisphere at…
Spatially Homogeneous Universes with Late-Time Anisotropy
Andrei Constantin, Thomas R. Harvey, Sebastian von Hausegger +1
The cosmological principle asserts that on sufficiently large scales the Universe is homogeneous and isotropic on spatial slices. To deviate from this principle requires a departur…
A Challenge to the Standard Cosmological Model
Nathan Secrest, Sebastian von Hausegger, Mohamed Rameez +2
We present the first joint analysis of catalogs of radio galaxies and quasars to determine if their sky distribution is consistent with the standard CDM model of cosmology. This…
Accurate Baryon Acoustic Oscillations reconstruction via semi-discrete optimal transport
Sebastian von Hausegger, Bruno Lévy, Roya Mohayaee
Optimal transport theory has recently reemerged as a vastly resourceful field of mathematics with elegant applications across physics and computer science. Harnessing methods from…
CMB foreground measurements through broad-band radio spectro-polarimetry: prospects of the SKA-MPG telescope
Aritra Basu, Dominik J. Schwarz, Hans-Rainer Klöckner +4
Precise measurement of the foreground synchrotron emission, which contaminates the faint polarized cosmic microwave background radiation (CMB), is a major challenge for the next-ge…
A blind search for a common signal in gravitational wave detectors
Hao Liu, James Creswell, Sebastian von Hausegger +2
We propose a blind, template-free method for the extraction of a common signal between the Hanford and Livingston detectors and apply it especially to the GW150914 event. We constr…
Towards understanding the Planck thermal dust models
Hao Liu, Sebastian von Hausegger, Pavel Naselsky
Understanding the properties of dust emission in the microwave domain is an important premise for the next generation of cosmic microwave background (CMB) experiments, devoted to t…
Footprints of Loop I on Cosmic Microwave Background Maps
Sebastian von Hausegger, Hao Liu, Philipp Mertsch +1
Cosmology has made enormous progress through studies of the cosmic microwave background, however the subtle signals being now sought such as B-mode polarisation due to primordial g…
Skewness and Kurtosis as Indicators of Non-Gaussianity in Galactic Foreground Maps
Assaf Ben-David, Sebastian von Hausegger, Andrew D. Jackson
Observational cosmology is entering an era in which high precision will be required in both measurement and data analysis. Accuracy, however, can only be achieved with a thorough u…
The Morphology of the Anomalous Microwave Emission in the Planck 2015 data release
Sebastian von Hausegger, Hao Liu
We calculate weighted mosaic correlations between the recently published Planck 2015 foreground maps - both anomalous microwave emission (AME) maps, free-free emission, synchrotron…
