Insights on the Spectral Signatures of Stellar Activity and Planets from PCA
Allen B. Davis, Jessi Cisewski, Xavier Dumusque +2
Photospheric velocities and stellar activity features such as spots and faculae produce measurable radial velocity signals that currently obscure the detection of sub-meter-per-sec…
The Velocity Distribution Function of Galaxy Clusters as a Cosmological Probe
M. Ntampaka, H. Trac, J. Cisewski +1
We present a new approach for quantifying the abundance of galaxy clusters and constraining cosmological parameters using dynamical measurements. In the standard method, galaxy lin…
The Eccentricity Distribution of Short-Period Planet Candidates Detected by Kepler in Occultation
Megan Shabram, Brice-Olivier Demory, Jessi Cisewski +2
We characterize the eccentricity distribution of a sample of ~50 short-period planet candidates using transit and occultation measurements from NASA's Kepler Mission. First, we eva…
cosmoabc: Likelihood-free inference via Population Monte Carlo Approximate Bayesian Computation
E. E. O. Ishida, S. D. P. Vitenti, M. Penna-Lima +5
Approximate Bayesian Computation (ABC) enables parameter inference for complex physical systems in cases where the true likelihood function is unknown, unavailable, or computationa…
Functional Regression for Quasar Spectra
Mattia Ciollaro, Jessi Cisewski, Peter Freeman +4
The Lyman-alpha forest is a portion of the observed light spectrum of distant galactic nuclei which allows us to probe remote regions of the Universe that are otherwise inaccessibl…
Nonparametric 3D map of the IGM using the Lyman-alpha forest
Jessi Cisewski, Rupert A. C. Croft, Peter E. Freeman +4
Visualizing the high-redshift Universe is difficult due to the dearth of available data; however, the Lyman-alpha forest provides a means to map the intergalactic medium at redshif…
