Exoplanet Detection using Machine Learning

1 code implementation28 Nov 2020 Abhishek Malik, Benjamin P. Moster, Christian Obermeier

For the Transiting Exoplanet Survey Satellite (TESS) data, we found our method can classify light curves with an accuracy of 0. 98, and is able to identify planets with a recall of 0. 82 at a precision of 0. 63.

GalaxyNet: Connecting galaxies and dark matter haloes with deep neural networks and reinforcement learning in large volumes

no code implementations25 May 2020 Benjamin P. Moster, Thorsten Naab, Magnus Lindström, Joseph A. O'Leary

GalaxyNet is then trained with a reinforcement learning approach: for a fixed set of weights and biases, we compute the galaxy properties for all haloes and then derive mock statistics (stellar mass functions, cosmic and specific SFRs, quenched fractions, and clustering).

EMERGE - An empirical model for the formation of galaxies since $z\sim10$

1 code implementation15 May 2017 Benjamin P. Moster, Thorsten Naab, Simon D. M. White

Galaxies that are quenched at $z=0$ typically have a higher peak star formation rate compared to their star-forming counterparts.

A Cosmic Variance Cookbook

1 code implementation11 Jan 2010 Benjamin P. Moster, Rachel S. Somerville, Jeffrey A. Newman, Hans-Walter Rix

This implies that cosmic variance is a significant source of uncertainty at z=2 for small fields and massive galaxies, while for larger fields and intermediate mass galaxies cosmic variance is less serious.
