Non-local-in-time structure formation and sixth-order galaxy bias
Alex Edison, Matthew Lewandowski, Leonardo Senatore
We present a systematic construction of the non-local-in-time galaxy bias expansion in the Effective Field Theory of Large-Scale Structure. In order to fully capture time non-local…
Efficient evaluation of the dark-matter two-loop power spectrum in the EFT of LSS
Charalampos Anastasiou, Andrea Favorito, Matthew Lewandowski +2
Rapid progress in cosmological Large Scale Structure (LSS) surveys motivates precise theoretical predictions. The Effective Field Theory of Large-Scale Structure (EFTofLSS) is rout…
The Spectroscopic Stage-5 Experiment
Robert Besuner, Arjun Dey, Alex Drlica-Wagner +106
The existence, properties, and dynamics of the dark sectors of our universe pose fundamental challenges to our current model of physics, and large-scale astronomical surveys may be…
Direct signatures of the formation time of galaxies
Yaniv Donath, Matthew Lewandowski, Leonardo Senatore
We show that it is possible to directly measure the formation time of galaxies using large-scale structure. In particular, we show that the large-scale distribution of galaxies is…

Guido D'Amico, Matthew Lewandowski, Leonardo Senatore +1
We analyze the power spectrum and the bispectrum of BOSS galaxy-clustering data using the prediction from the Effective Field Theory of Large-Scale Structure at one-loop order for…
Baryonic effects in the Effective Field Theory of Large-Scale Structure and an analytic recipe for lensing in CMB-S4
Diogo P. L. Bragança, Matthew Lewandowski, David Sekera +2
Upcoming Large-Scale Structure surveys will likely become the next leading sources of cosmological information, making it crucial to have a precise understanding of the influence o…
