Deep+Wide Lensing Surveys will Provide Exquisite Measurements of the Dark Matter Halos of Dwarf Galaxies
Alexie Leauthaud, Sukhdeep Singh, Yifei Luo +5
The advent of new deep+wide photometric lensing surveys will open up the possibility of direct measurements of the dark matter halos of dwarf galaxies. The HSC wide survey will be…
Astrophysical Tests of Dark Matter with Maunakea Spectroscopic Explorer
Ting S. Li, Manoj Kaplinghat, Keith Bechtol +27
We discuss how astrophysical observations with the Maunakea Spectroscopic Explorer (MSE), a high-multiplexity (about 4300 fibers), wide field-of-view (1.5 square degree), large tel…
The Two-Halo Term in Stacked Thermal Sunyaev-Zel'dovich Measurements: Implications for Self-Similarity
J. Colin Hill, Eric J. Baxter, Adam Lidz +2
The relation between the mass and integrated electron pressure of galaxy group and cluster halos can be probed by stacking maps of the thermal Sunyaev-Zel'dovich (tSZ) effect. Perh…
The Stacked Thermal SZ Signal of Locally Brightest Galaxies in Planck Full Mission Data: Evidence for Galaxy Feedback?
Johnny P. Greco, J. Colin Hill, David N. Spergel +1
We use the Planck full mission temperature maps to examine the stacked thermal Sunyaev-Zel'dovich (tSZ) signal of 188042 "locally brightest galaxies'" (LBGs) selected from the Sloa…
Measurement of the Mass and Stellar Population Distribution in M82 with the LBT
Johnny P. Greco, Paul Martini, Todd A. Thompson
We present a K-band spectroscopic study of the stellar and gas kinematics, mass distribution, and stellar populations of the archetypical starburst galaxy M82. Our results are base…
