Edward D. Ramirez's Projects

allsky-point-source-detection icon allsky-point-source-detection

This repo provides code for detecting point sources on a sphere (i.e., the sky) by applying the continuous wavelet transform on raw count data. We use this tool to detect faint gamma-ray point sources from Fermi-LAT. See my skysearch repo for a pipeline.

derivative-tinygp icon derivative-tinygp

Summary notebooks using derivative gaussian processes with tinygp. We implement a 2D derivative gaussian process and successfully use derivatives to regularize SVI fits with a gaussian process model..

dmbinaries icon dmbinaries

Code used to constrain dark matter substructure in the solar neighborhood with Gaia eDR3 wide binaries.

lobbying-market icon lobbying-market

A study of the possible relationship between company lobbying activity and company stock price movement.

py_cwt2d icon py_cwt2d

Simple 2D continuous wavelet transform implementation in Python

skysearch icon skysearch

Pipeline for finding point sources in Fermi-LAT data with the continuous wavelet transform. For a tutorial that describes how this code works, see the allsky-point-source-detection repo.

sparse-tinygp icon sparse-tinygp

Bayesian inference using sparse gaussian processes from tinygp. Examples include 1D and 2D implementation.

svi-dist-fit icon svi-dist-fit

Novel technique to fit a target distribution with a class of distributions using SVI (via NumPyro). Unlike standard SVI, our "data" is a distribution rather than a finite collection of samples.

wavelet-density-estimation icon wavelet-density-estimation

1D Density Estimation with the Haar Wavelet. Application is to separate point sources from a background distribution.
