A quantitative comparison between velocity dependent SIDM cross sections constrained by the gravothermal and isothermal models
Shengqi Yang, Fangzhou Jiang, Andrew Benson +6
One necessary step for probing the nature of self-interacting dark matter (SIDM) particles with astrophysical observations is to pin down any possible velocity dependence in the SI…
Extragalactic Science with the Experiment for Cryogenic Large-aperture Intensity Mapping
Anthony R. Pullen, Patrick C. Breysse, Trevor Oxholm +14
The EXperiment for Cryogenic Large-Aperture Intensity Mapping (EXCLAIM) is a balloon-borne cryogenic telescope that will survey the spectrum of diffuse emission from both the Milky…
A semi-analytic study of self-interacting dark-matter haloes with baryons
Fangzhou Jiang, Andrew Benson, Philip F. Hopkins +8
We combine the isothermal Jeans model and the model of adiabatic halo contraction into a simple semi-analytic procedure for computing the density profile of self-interacting dark-m…
Gravothermal solutions of SIDM halos: mapping from constant to velocity-dependent cross section
Shengqi Yang, Xiaolong Du, Zhichao Carton Zeng +4
The scale-free gravothermal fluid formalism has long proved effective in describing the evolution of self-interacting dark matter halos with a constant dark matter particle cross s…
On estimating the cosmic molecular gas density from CO Line Intensity Mapping observations
Patrick C. Breysse, Shengqi Yang, Rachel S. Somerville +3
The Millimeter-wave Intensity Mapping Experiment (mmIME) recently reported a detection of excess spatial fluctuations at a wavelength of 3 mm, which can be attributed to unresolved…
A new calibration method of sub-halo orbital evolution for semi-analytic models
Shengqi Yang, Xiaolong Du, Andrew J. Benson +2
Understanding the non-linear dynamics of satellite halos (a.k.a. "sub-halos") is important for predicting the abundance and distribution of dark matter substructures and satellite…
Evidence for CII diffuse line emission at redshift
Shengqi Yang, Anthony R. Pullen, Eric R. Switzer
CII is one of the brightest emission lines from star-forming galaxies and is an excellent tracer for star formation. Recent work measured the CII emission line amplitude for redshi…
Intensity Mapping in the Presence of Foregrounds and Correlated Continuum Emission
E. R. Switzer, C. J. Anderson, A. R. Pullen +1
Intensity mapping has attracted significant interest as an approach to measure the properties of the interstellar medium in typical galaxies at high redshift. Intensity mapping mea…
Calibrating magnification bias for the statistic to test general relativity
Shengqi Yang, Anthony R. Pullen
We assess the effect of magnification bias on the statistic for probing gravity. , a statistic constructed from power spectrum estimates of both weak lensing and redshif…
