Galaxy cluster mass estimation with deep learning and hydrodynamical simulations
We evaluate the ability of Convolutional Neural Networks (CNNs) to predict galaxy cluster masses in the BAHAMAS hydrodynamical simulations. We train four separate single-channel networks using: stella...

Bridging geometric and wave optics through the complex plane
Much of the lensing effects in astrophysics can be adequately described using geometric optics, where light from a point source can be split into multiple magnified images. In coherent sources, such ...

Probing stellar initial mass function with CNO isotopes
All measurements of cosmic star formation must assume the stellar initial mass function (IMF) to extrapolate from the star-formation rate (SFR) measured for massive stars to the total SFR. Traditional...
