We present a clustering analysis of the BOSS DR12 CMASS galaxy sample, combining measurements of the galaxy two-point correlation function and density-split clustering down to a scale of $1\, h^{-1}{\rm Mpc}$.

Our results show that not removing the PSF light can overestimate the IHL SB by $\sim$ 1. 7 mag arcsec$^{-2}$ and the $\mathrm{f_{IHL}}$ by $\sim$ 30%.
Astrophysics of Galaxies
We describe enhancements to the digest2 software, a short-arc orbit classifier for heliocentric orbits.
Earth and Planetary Astrophysics Instrumentation and Methods for Astrophysics
Here we use a suite of 1D hydrodynamic simulations and impedance match calculations to quantify the effect that pre-impact surface conditions (such as atmospheric pressure and presence of an ocean) have on the efficiency of atmospheric and ocean loss from proto-planets during giant impacts.
Earth and Planetary Astrophysics Geophysics
We present a simulation-based model that is able to capture the cosmological dependence of the full shape of the density-split clustering (DSC) statistics down to intra-halo scales.

Assuming a source at redshift 2. 0 and an EPL+XS lens at redshift 0. 3, we find that the bias can be reduced, but not eliminated, if we limit the sample to systems with annulus lengths $\Delta r_{1, 2} \gtrsim 0. 3$ arcsec.

If the quasars have a lower response to local PNG, our optimal constraint becomes $-23<f_{\rm NL}<21$ at $68\%$, with an improvement of $30\%$ over standard analyses.
Cosmology and Nongalactic Astrophysics
We compare the [CII] line profiles to observations of CO and HI and find that likely the majority ($>55$%) of the [CII] emission in the outflow is associated with the neutral atomic medium.
Astrophysics of Galaxies
The core of our algorithm is based on an estimation of the magnetic field gradients by a least-square reconstruction on the unstructured mesh, which we also used in the companion paper for Ohmic and ambipolar diffusion.
Instrumentation and Methods for Astrophysics
To guide our steps in this, we perform a sensitivity analysis of SBI for galaxy clustering on various components of the cosmological simulations: gravity model, halo-finder and the galaxy-halo distribution models (halo-occupation distribution, HOD).
