Dark Energy Survey Year 3: Blue Shear

J. McCullough, A. Amon, E. Legnani +115

Modeling the intrinsic alignment (IA) of galaxies poses a challenge to weak lensing analyses. The Dark Energy Survey is expected to be less impacted by IA when limited to blue, sta…

Outbursts Upon Cooling of Low-Temperature Binary Mixtures: Experiments and Their Planetary Implications

S. M. Raposa, A. E. Engle, S. P. Tan +7

For many binary mixtures, the three-phase solid-liquid-vapor equilibrium curve has intermediate pressures that are higher than the pressure at the two pure triple points. This curv…

Spin states of X-complex asteroids in the inner main belt -- I. Investigating the Athor and Zita collisional families

D. Athanasopoulos, J. Hanuš, C. Avdellidou +14

The aim of our study is to characterise the spin states of the members of the Athor and Zita collisional families and test whether these members have a spin distribution consistent…

Superclustering with the Atacama Cosmology Telescope and Dark Energy Survey: II. Anisotropic large-scale coherence in hot gas, galaxies, and dark matter

M. Lokken, A. van Engelen, M. Aguena +73

Statistics that capture the directional dependence of the baryon distribution in the cosmic web enable unique tests of cosmology and astrophysical feedback. We use constrained orie…

Properties of outer solar system pebbles during planetesimal formation from meteor observations

Peter Jenniskens, Paul R. Estrada, Stuart Pilorz +42

In the late stages of accretion leading up to the formation of planetesimals, particles grew to pebbles the size of 1-mm to tens of cm. That is the same size range that dominates t…

Enhancing weak lensing redshift distribution characterization by optimizing the Dark Energy Survey Self-Organizing Map Photo-z method

A. Campos, B. Yin, S. Dodelson +111

Characterization of the redshift distribution of ensembles of galaxies is pivotal for large scale structure cosmological studies. In this work, we focus on improving the Self-Organ…
