Mitigating the noise of DESI mocks using analytic control variates
Boryana Hadzhiyska, Martin J. White, Xinyi Chen +30
In order to address fundamental questions related to the expansion history of the Universe and its primordial nature with the next generation of galaxy experiments, we need to mode…
Effective cosmic density field reconstruction with convolutional neural network
Xinyi Chen, Fangzhou Zhu, Sasha Gaines +1
We present a cosmic density field reconstruction method that augments the traditional reconstruction algorithms with a convolutional neural network (CNN). Following Shallue Ei…
A Search for In-Situ Field OB Star Formation in the Small Magellanic Cloud
Irene Vargas-Salazar, M. S. Oey, Jesse R. Barnes +4
Whether any OB stars form in isolation is a question central to theories of massive star formation. To address this, we search for tiny, sparse clusters around 210 field OB stars f…
Dark Energy Survey Year 1 Results: Cosmological Constraints from Cluster Abundances and Weak Lensing
DES Collaboration, Tim Abbott, Michel Aguena +129
We perform a joint analysis of the counts and weak lensing signal of redMaPPer clusters selected from the Dark Energy Survey (DES) Year 1 dataset. Our analysis uses the same shear…
Chandra Follow-Up of the SDSS DR8 redMaPPer Catalog Using the MATCha Pipeline
Devon L. Hollowood, Tesla Jeltema, Xinyi Chen +15
In order to place constraints on cosmology through optical surveys of galaxy clusters, one must first understand the properties of those clusters. To this end, we introduce the Mas…
