Fisher Forecasts for Cosmological Yields from 3x2 Analysis of the Roman Space Telescope High Latitude Imaging Survey
Description:
The High Latitude Imaging Survey (HLIS) of NASA's Nancy Grace Roman Space Telescope will provide powerful tests of cosmological models through sensitive measurements of cosmic shear, galaxy-galaxy lensing (GGL), and galaxy clustering.

Cluster Center Detection
Description:
We would like to find a simple cluster detection scheme that is easy to implement in simulation-based forward modeling.

The Roman View of Strong Gravitational Lenses
Description:
We present a yield simulation of detectable galaxy-galaxy strong gravitational lenses in Roman's High Latitude Wide Area Survey (HLWAS). For a fiducial case of single 146-second exposures, we predict around 160,000 detectable strong lenses in the HLWAS.

Deciphering Baryonic Feedback from ACT tSZ Galaxy Clusters
Description:
The next generation of cosmology surveys will probe the matter distribution of the universe to unparalleled precision. To match this level of precision in cosmological parameter estimation, we need to use information at small scales of ∼ 1 Mpc

Constraining Inflation Models with spinning voids
Description:
New diagnostic method that constrains the running of the scalar spectral index αₛ of primordial density fluctuations using the rotation of void, observable as redshift asymmetry across their projected spin axes.

Constraining Evolving and Spatially Varying Dark Energy
Description:
Ultralight axions with a mass of 10^-33 eV offer one explanation for the recent hints of evolving dark energy. If they comprise 100% of the dark energy today, they must carry isocurvature fluctuations that may have an observable signal in future lensing.

Clustering of DESI galaxies split by thermal Sunyaev-Zeldovich effect
Description:
We use the Atacama Cosmology Telescope (ACT) thermal Sunyaev-Zeldovich data to separate Dark Energy Spectroscopic Instrument (DESI) Luminous Red Galaxies (LRGs) into distinct subpopulations corresponding to different densities and biases independently of

TITAN DR1: The Type 1A Supernovae Trove from ATLAS in the Nearby Universe
Description:
TITAN DR1 presents the largest low-redshift sample of spectroscopically confirmed Type Ia supernovae to date, built from uniform, high-cadence ATLAS observations and rigorously calibrated at the millimagnitude level.

Thermal and electrical properties of prototype readout components for CMB-54
Description:
I present measurements of the electrical properties of SQUID series array (SSA) amplifiers under multiple configurations. I also report measurements of the thermal conductivity of materials commonly used in cryogenic wiring.

Scattering Transform on the Sphere Applied to Weak Lensing
Description:
This work uses spherical scattering transform, a higher-order statistics method, to weak gravitational lensing data in order to improve cosmological parameter inference.

Detecting polar ring galaxies via deep learning
Description:
Polar ring galaxies (PRGs) are a special kind of galaxies that are rare and less studied. We make use of Convoluted Neural Network (CNN) to detect PRGs from images from sky survey.
