A weak lensing perspective on nonlinear structure formation with fuzzy dark matter
Alexander Kunkel, Tzihong Chiueh, Björn Malte Schäfer
We investigate nonlinear structure formation in the fuzzy dark matter (FDM) model in comparison to cold dark matter (CDM) models from a weak lensing perspective using perturbative…
Cornering Extended Starobinsky Inflation with CMB and SKA
Tanmoy Modak, Lennart Röver, Björn Malte Schäfer +2
Starobinsky inflation is an attractive, fundamental model to explain the Planck measurements, and its higher-order extension may allow us to probe quantum gravity effects. We show…
Partition function approach to non-Gaussian likelihoods: Formalism and expansions for weakly non-Gaussian cosmological inference
Lennart Röver, Lea Carlotta Bartels, Björn Malte Schäfer
Non-Gaussian likelihoods, ubiquitous throughout cosmology, are a direct consequence of nonlinearities in the physical model. Their treatment requires Monte-Carlo Markov-chain or mo…
Etherington duality breaking: gravitational lensing in non-metric spacetimes versus intrinsic alignments
Eileen Sophie Giesel, Basundhara Ghosh, Björn Malte Schäfer
The Etherington distance duality relation is well-established for metric theories of gravity, and confirms the duality between the luminosity distance and the angular diameter dist…
On the Cosmic Web Elongation in Fuzzy Dark Matter Cosmologies: Effects on Density Profiles, Shapes and Alignments of Halos
Tibor Dome, Anastasia Fialkov, Philip Mocz +3
The fuzzy dark matter (FDM) scenario has received increased attention in recent years due to the small-scale challenges of the vanilla Lambda cold dark matter (CDM) cosmological…
