We constrain cosmology and baryonic feedback scenarios with a joint analysis of weak lensing, galaxy clustering, cosmic microwave background (CMB) lensing, and their cross-correlations (so-called 62) using data from the Dark Energy Survey (DES) Y1 and the Planck satellite mission. Noteworthy features of our 62 pipeline are: We extend CMB lensing cross-correlation measurements to a band surrounding the DES Y1 footprint (a gain in pairs), and we develop analytic covariance capabilities that account for different footprints and all cross-terms in the 62 analysis. We also measure the DES Y1 cosmic shear two-point correlation function (2PCF) down to , but find that going below does not increase cosmological information due to shape noise. We model baryonic physics uncertainties via the amplitude of Principal Components (PCs) derived from a set of hydro-simulations. Given our statistical uncertainties, varying the first PC amplitude is sufficient to model small-scale cosmic shear 2PCF. For DES Y1+Planck 62 we find , comparable to the 52 result of DES Y3+SPT/Planck . Combined with our most informative cosmology priors -- baryon acoustic oscillation (BAO), big bang nucleosynthesis (BBN), type Ia supernovae (SNe Ia), and Planck 2018 EE+lowE, we measure . Regarding baryonic physics constraints, our 62 analysis finds . Combined with the aforementioned priors, it improves the constraint to . For comparison, the strongest feedback scenario considered in this paper, the cosmo-OWLS AGN ( K), corresponds to .
