Vision Transformers for Cosmological Fields: Application to Weak Lensing Mass Maps
Jash Kakadia, Shubh Agrawal, Kunhao Zhong +1
Weak gravitational lensing is a powerful probe of the universe's growth history. While traditional two-point statistics capture only the Gaussian features of the convergence field,…
The Speed of Gravity and the Fate of Dark Energy
Jeremy Sakstein, Bhuvnesh Jain
On August 17 2017, observatories worldwide made a landmark detection: gravitational waves and light from a binary neutron star merger. This event revolutionized our unde…
High-resolution weak lensing mass mapping from DES-Y3 data using diffusion-based prior
Supranta S. Boruah, Michael Jacob, Bhuvnesh Jain +2
High-resolution mapping of cosmic mass distribution is essential for a variety of astrophysical applications including understanding cosmic structure formation, and galaxy formatio…
Tests of Evolving Dark Energy with Geometric Probes of the Late-Time Universe
Kunhao Zhong, Bhuvnesh Jain
Recent results from the Dark Energy Spectroscopic Instrument (DESI) have shown a strong statistical preference for a time-evolving dark energy model over CDM when combining BAO,…
Diffusion-based mass map reconstruction from weak lensing data
Supranta S. Boruah, Michael Jacob, Bhuvnesh Jain
Diffusion models have been used in cosmological applications as a generative model for fast simulations and to reconstruct underlying cosmological fields or astrophysical images fr…
Fast Generation of Weak Lensing Maps with Analytical Point Transformation Functions
Kunhao Zhong, Gary Bernstein, Supranta S. Boruah +2
Nonlinear cosmological fields like galaxy density and lensing convergence can be approximately related to Gaussian fields via analytic point transforms. The lognormal transform (LN…
Dark Energy and CMB
S. Dodelson, K. Honscheid, K. Abazajian +9
The American Physical Society's Division of Particles and Fields initiated a long-term planning exercise over 2012-13, with the goal of developing the community's long term aspirat…
Probing Dark Energy via Weak Gravitational Lensing with the SuperNova Acceleration Probe (SNAP)
SNAP Collaboration
SNAP is a candidate for the Joint Dark Energy Mission (JDEM) that seeks to place constraints on the dark energy using two distinct methods. The first, Type Ia SN, is discussed in a…
Dark Energy and the CMB
S. Dodelson, L. Knox
We find that current Cosmic Microwave Background (CMB) anisotropy data strongly constrain the mean spatial curvature of the Universe to be near zero, or, equivalently, the total en…
