Beyond the 3rd moment: A practical study of using lensing convergence CDFs for cosmology with DES Y3

D. Anbajagane, C. Chang, A. Banerjee +95

Widefield surveys of the sky probe many clustered scalar fields -- such as galaxy counts, lensing potential, gas pressure, etc. -- that are sensitive to different cosmological and…

Detection of the significant impact of source clustering on higher-order statistics with DES Year 3 weak gravitational lensing data

M. Gatti, N. Jeffrey, L. Whiteway +98

We demonstrate and measure the impact of source galaxy clustering on higher-order summary statistics of weak gravitational lensing data. By comparing simulated data with galaxies t…

DES Y3 + KiDS-1000: Consistent cosmology combining cosmic shear surveys

Dark Energy Survey, Kilo-Degree Survey Collaboration, : +160

We present a joint cosmic shear analysis of the Dark Energy Survey (DES Y3) and the Kilo-Degree Survey (KiDS-1000) in a collaborative effort between the two survey teams. We find c…

The Dark Energy Survey Year 3 and eBOSS: constraining galaxy intrinsic alignments across luminosity and colour space

S. Samuroff, R. Mandelbaum, J. Blazek +104

We present direct constraints on galaxy intrinsic alignments using the Dark Energy Survey Year 3 (DES Y3), the Extended Baryon Oscillation Spectroscopic Survey (eBOSS) and its prec…

Non-local contribution from small scales in galaxy-galaxy lensing: Comparison of mitigation schemes

J. Prat, G. Zacharegkas, Y. Park +112

Recent cosmological analyses with large-scale structure and weak lensing measurements, usually referred to as 32pt, had to discard a lot of signal-to-noise from small scale…

The Dark Energy Survey Year 3 high redshift sample: Selection, characterization and analysis of galaxy clustering

C. Sánchez, A. Alarcon, G. M. Bernstein +97

The fiducial cosmological analyses of imaging galaxy surveys like the Dark Energy Survey (DES) typically probe the Universe at redshifts . This is mainly because of the limi…
