PI:  Ian Dell’Antonio

Ian Dell’Antonio has been a professor at Brown since 2000.  Before that, he was a postdoc at the National Optical Astronomy Observatories (1998-2000) and postdoctoral researcher at Bell Laboratories (1995-1998).  His research covers the study of galaxy clusters as probes of dark energy, dark matter, and as laboratories for galaxy evolution.

 

PhD Student:  Shenming Fu

 

Shenming Fu is a PhD student in this research group and a member of LSST DESC. He has been studying the effects of image blending on galaxy cluster lensing shear measurements with image simulations, and he is leading the processing of the DECam exposures for the LoVoCCS clusters with LSST Science Pipelines. He has the experience of using the WIYN telescope at KPNO and the Blanco telescope at CTIO to capture the images of galaxy clusters. He is also working on developing a cluster mass measurement pipeline with the researchers in DESC.  His research interests include gravitational lensing in galaxy clusters, photometric redshifts, and galaxy cluster cosmology. He was the organizer of the BASS/CFPU seminars in 2018-2020, worked as a TA for astronomy labs in 2017 and 2018, and participated in Brown University’s Sidewalk Astronomy as public outreach in 2018 and 2019.

 

Undergraduate Students (2020-2021)

 

Isabel Horst

 

Taylor Knapp: Taylor Knapp is an undergraduate from North Carolina planning to major in astrophysics and mathematics. She is published in Data in Brief for experimental work with millimeter-wave DC interactions with organic photoresponsive materials. She has previously worked with the Duke University Neutrino and Cosmology Group investigating the behavior of neutrinos emitted from neutron star mergers and detected with Super Kamioka. Currently, she is assisting in processing DECam exposures for the LoVoCCS clusters with LSST Science Pipelines and is interested in the correlations generated by galaxy colors. She has also done investigative work in the topological Teichmuller space of tori and expressing higher dimensional thermodynamics. Her research interests include gravitational lensing, general relativity, and applications of differential geometry to cosmology. Taylor is also a coordinator for the Physics Departmental Undergraduate Group, Class Coordinating Board ’23 President, and a member of the Brown University Running Club.
