The Lyman-$α$ Forest from LBGs: First 3D Correlation Measurement with DESI and Prospects for Cosmology
The Lyman-$α$ (Ly$α$) forest is a key tracer of large-scale structure at redshifts z > 2, traditionally studied using spectra of quasars. Here, we explore the viability Lyman Break Galaxies (LBGs) as alternative background sources for Ly$α$ forest studies. We analyze 4,151 Ly$α$ forest skewers extracted from LBG spectra obtained in the DESI pilot surveys in the COSMOS and XMM-LSS fields. We present the first measurement of the Ly$α$ forest auto-correlation function derived exclusively from…

Well. That was pretty easy. Boot process secured and prettified with #limine #nixos

Was walking by the counter, saw a pepper lying on it, thought why not, my limoncello is already a hybrid limon-aran-cello, let's make it totally mongrel, and threw the pepper in. Now it's even more awesome! In other news, I've been banned from ever returning to Italy.

A gradient boosting and broadband approach to finding Lyman-α emitting galaxies beyond narrowband surveys
In this work, we test whether gradient-boosting algorithms, trained on broadband photometric data from traditional Lyman-$α$ emitting (LAE) surveys, can efficiently and accurately identify LAE candidates from typical star-forming galaxies at similar redshifts and brightness levels. Using galaxy samples at $z \in [2,6]$ derived from the COSMOS2020 and SC4K catalogs, we trained gradient-boosting machine-learning algorithms (LGBM, XGBoost, and CatBoost) using optical and near-infrared broadband p…

#limine looks interesting. A non-annoying way to get secure boot and a pretty boot menu in #nixos? Sign me up.

While looking in vain for comet Lemmon - already too low - from Bochum, Germany, yesterday (28 October) the setting #Moon suddenly broke through the clouds, at -26° declination. Some consolation prize ...
