Velocityformer: Broken-Symmetry-Matched Equivariant Graph Transformers for Cosmological Velocity Reconstruction
Tilman Tröster, David Mirkovic, Veronika Oehl +1
Precise measurement of the kinematic Sunyaev-Zel'dovich (kSZ) effect - a probe of the large-scale distribution of baryonic matter, a key observable for cosmological inference - req…
The Non-Gaussian Weak-Lensing Likelihood: A Multivariate Copula Construction and Impact on Cosmological Constraints
Veronika Oehl, Tilman Tröster
We present a framework to compute non-Gaussian likelihoods for two-point correlation functions. The non-Gaussianity is most pronounced on large scales that will be well-measured by…
WAFER: A new method to retrieve sun-induced fluorescence based on spectral wavelet decompositions
Veronika Oehl, Alexander Damm
Sun-induced fluorescence (SIF) as a close remote sensing based proxy for photosynthesis is accepted as a useful measure to remotely monitor vegetation health and gross primary prod…
Consequences of Non-Gaussian Instrumental Noise in Perturbed Nulling Interferometers
Felix A. Dannert, Philipp A. Huber, Thomas Birbacher +6
With the astrophysics community working towards the first observations and characterizations of Earth-like exoplanets, interest in space-based nulling interferometry has been renew…
The exact non-Gaussian weak lensing likelihood: A framework to calculate analytic likelihoods for correlation functions on masked Gaussian random fields
Veronika Oehl, Tilman Tröster
We present exact non-Gaussian joint likelihoods for auto- and cross-correlation functions on arbitrarily masked spherical Gaussian random fields. Our considerations apply to spin-0…
Cloudlet capture by Transitional Disk and FU Orionis stars
Cornelis Petrus Dullemond, Michael Küffmeier, Felipe Goicovic +3
After its formation, a young star spends some time traversing the molecular cloud complex in which it was born. It is therefore not unlikely that, well after the initial cloud coll…
