October 6, 2023 @ 12:00 pm - 1:00 pm
Date: Friday, October 6, 2023

Title: The Merian Survey: Characterizing dark matter and feedback in star-forming dwarf galaxies with medium-band filters on DECam
Abstract: The Merian survey is an ongoing medium-band imaging survey on the CTIO 4-meter Blanco telescope. With two custom made medium-band filters on DECam, we expect to detect 80,000 star-forming dwarf galaxies at z~0.1 in the HSC-SSP wide field, aiming to characterize dark matter halo and stellar feedback in dwarf galaxies. The Merian survey will allow us to measure the full dark matter profile of dwarf galaxies via weak gravitational lensing for the first time. In this talk, I will present how we optimized the Merian filter design for our science goals, and discuss the filter performance with mock and actual Merian data. I will also show that the Merian medium-band filter set is able to select objects at higher redshifts out to z~4.8.
