Disentangling the galactic and intergalactic components in 313 observed Lyman-alpha line profiles between redshift 0 and 5

Siddhartha Gurung-López, Chris Byrohl, Max Grönke, Daniele Spinoso et autres

Lyman-Alpha (Ly α ) photons emitted in star-forming galaxies undergo complex radiative transfer through the interstellar (ISM), circumgalactic (CGM), and intergalactic medium (IGM), imprinting characteristic signatures on their observed line profiles. We use the open-source package (redshift Estimator for Line profiles of …

From stars to the Cosmic Web: Exploring 3D printing as a tool for inclusive astronomy communication

Amelia Ortiz-Gil, Vicent Martínez García, Emilio Terol, Alberto Fernández-Soto et autres

The use of physical 3D models in astronomy communication with the public has already been proven as an effective way to disseminate science, with the benefit of including the blind and visually impaired community. We present here a set of ten new …

Exploring the spatially-resolved capabilities of the J-PAS survey with Py2DJPAS

J. E. Rodríguez-Martín, L. A. Díaz-García, Rosa M. González Delgado, G. Martínez-Solaeche et autres

We present Py2DJPAS, a Python-based tool to automate the analysis of spatially resolved galaxies in the \textbf{miniJPAS} survey, a 1~deg$^2$ precursor of the J-PAS survey, using the same filter system, telescope, and Pathfinder camera. Py2DJPAS streamlines the entire workflow: downloading scientific images …

zELDA II: Reconstruction of galactic Lyman-alpha spectra attenuated by the intergalactic medium using neural networks

Siddhartha Gurung-López, Chris Byrohl, Max Grönke, Daniele Spinoso et autres

Context . The observed Lyman-alpha (Ly α ) line profile is a convolution of the complex Ly α radiative transfer taking place in the interstellar, circumgalactic, and intergalactic media (ISM, CGM, and IGM, respectively). Discerning the different components of the Ly α …

zELDA II: reconstruction of galactic Lyman-alpha spectra attenuated by the intergalactic medium using neural networks

Siddhartha Gurung-López, Chris Byrohl, Max Grönke, Daniele Spinoso et autres

The observed Lyman-Alpha (Lya) line profile is a convolution of the complex Lya radiative transfer taking place in the interstellar, circumgalactic and intergalactic medium (ISM, CGM, and IGM, respectively). Discerning the different components of the Lya line is crucial in order to …

The PAU Survey: The quasar Lyα and UV luminosity functions at 2.7 < z < 5.3

Alberto Torralba, Pablo Renard, Daniele Spinoso, P. Arnalte-Mur et autres

We present the Lyman-α (Lyα) and ultraviolet (UV) luminosity function (LF) in bins of redshift for quasars selected in the Physics of the Accelerating Universe Survey (PAUS). A sample of 915 objects was selected at 2.7 < z < 5.3 within an …

The PAU Survey: The quasar UV and Ly$α$ luminosity functions at $2.7

Alberto Torralba, Pablo Renard, Daniele Spinoso, P. Arnalte-Mur et autres

We present the Lyman-$α$ (Ly$α$) and ultraviolet (UV) luminosity function (LF), in bins of redshift, of quasars selected in the Physics of the Accelerating Universe Survey (PAUS). A sample of 915 objects was selected at $2.710^{44}$ ${\rm erg\,s}$$^{-1}$. In order to obtain …

The miniJPAS survey: Maximising the photo-z accuracy from multi-survey datasets with probability conflation

Antonio Hernán-Caballero, Mohammad Akhlaghi, C. López-Sanjuán, Héctor Vázquez Ramió et autres

We present a new method for obtaining photometric redshifts (photo-z) for sources observed by multiple photometric surveys using a combination (conflation) of the redshift probability distributions (PDZs) obtained independently from each survey. The conflation of the PDZs has several advantages over the …
