AESTRA II: Generative Spectral Modeling of the Sun as a Star for Precise Radial Velocities
Yan Liang, Joshua N. Winn, Peter Melchior +2
The detection of Earth analogs with extreme-precision radial velocities (EPRVs) is limited by spectral variability from stellar activity, telluric absorption, and instrumental syst…
Spatially Resolved Galaxy-Dust Modeling with Coupled Data-Driven Priors
Jared Siegel, Peter Melchior
A notorious problem in astronomy is the recovery of the true shape and spectral energy distribution (SED) of a galaxy despite attenuation by interstellar dust embedded in the same…
Inhomogeneous Dust Biases Photometric Redshifts and Stellar Masses for LSST
ChangHoon Hahn, Peter Melchior
Spectral energy distribution (SED) modeling is one of the main methods to estimate galaxy properties, such as photometric redshifts, , and stellar masses, , for extragalact…
Joint Cosmic Density Reconstruction from Photometric and Spectroscopic Samples
Benjamin Horowitz, Peter Melchior
We reconstruct the dark matter density field from spatially overlapping spectroscopic and photometric redshift catalogs through a forward modelling approach. Instead of directly in…
