Radio frequency interference mitigation using deep convolutional neural networks

jakeret/tf_unet 28 Sep 2016

We employ a special type of Convolutional Neural Network, the U-Net, that enables the classification of clean signal and RFI signatures in 2D time-ordered data acquired from a radio telescope.

$B$-mode forecast of CMB-Bh$\overline{a}$rat

dfm/emcee 24 Oct 2021

For a simplistic foreground model (only polarized dust and synchrotron), both component separation pipelines can achieve the desired sensitivity of ECHO, i. e. $\sigma (r =0) \sim (0. 4 - 0. 7)\times 10^{-3}$.

emcee: The MCMC Hammer

dfm/emcee 16 Feb 2012

The algorithm behind emcee has several advantages over traditional MCMC sampling methods and it has excellent performance as measured by the autocorrelation time (or function calls per independent sample).

The impact of spectroscopic incompleteness in direct calibration of redshift distributions for weak lensing surveys

JustGlowing/minisom 23 Mar 2020

We do so by simulating the process of assembling a spectroscopic sample (including observer-assigned confidence flags) and highlight the impacts of spectroscopic target selection and redshift failures.

A proposal for community driven and decentralized astronomical databases and the Open Exoplanet Catalogue

OpenExoplanetCatalogue/open_exoplanet_catalogue 29 Nov 2012

It is the only catalogue that can correctly represent the orbital structure of planets in arbitrary binary, triple and quadruple star systems, as well as orphan planets.

Introduction to astroML: Machine Learning for Astrophysics

astroML/astroML 18 Nov 2014

Astronomy and astrophysics are witnessing dramatic increases in data volume as detectors, telescopes and computers become ever more powerful.

Instrumentation and Methods for Astrophysics Blind astrometric calibration of arbitrary astronomical images

dstndstn/ 12 Oct 2009

We have built a reliable and robust system that takes as input an astronomical image, and returns as output the pointing, scale, and orientation of that image (the astrometric calibration or WCS information).
