Pinpointing the cosmic web between massive galaxy clusters I. The incidence of HI and OVI as WHIM tracers
Karen Martínez-Acosta, Nicolas Tejos, Ismael Pessa +6
At redshift z<1, the CDM paradigm predicts that 40-50\% of baryons reside in the warm-hot intergalactic medium (WHIM) within cosmic web filaments. Characterizing the physi…
A positive correlation between broad HI Ly absorptions and local overdensities of galaxies
Ismael Pessa, Nicolas Tejos, Karen Martinez-Acosta +3
A large fraction of the baryon budget at resides in large-scale filaments in the form of diffuse intergalactic gas, and numerous studies have reported a significant correlati…
A galactic outflow traced by its extended Mg II emission out to a kpc radius in the Hubble Ultra Deep Field with MUSE
Ismael Pessa, Lutz Wisotzki, Tanya Urrutia +12
We report the discovery of a rare Mg II 2796, 2803 doublet emission halo around a star forming galaxy with /M at in deep (9.…
The MUSE eXtremely Deep Field: Detections of circumgalactic SiII* emission at z>~2
Haruka Kusakabe, Valentin Mauerhofer, Anne Verhamme +17
The circumgalactic medium (CGM) serves as a baryon reservoir that connects galaxies to the intergalactic medium and fuels star formation. The spatial distribution of the metal-enri…
Slicing the cool circumgalactic medium along the major-axis of a star-forming galaxy at
S. Lopez, N. Tejos, L. F. Barrientos +13
We present spatially-resolved echelle spectroscopy of an intervening MgII-FeII-MgI absorption-line system detected at toward the giant gravitational arc PSZ1…
PyMUSE: a Python package for VLT/MUSE data
Ismael Pessa, Nicolas Tejos, Cristobal Moya
This is a companion Focus Demonstration article to the PyMUSE python package, demonstrating its usage and utilities for VLT/MUSE data analysis, that include a wide range of options…
A VLT/MUSE galaxy survey towards QSO Q1410: looking for a WHIM traced by BLAs in inter-cluster filaments
Ismael Pessa, Nicolas Tejos, L. Felipe Barrientos +7
Cosmological simulations predict that a significant fraction of the low- baryon budget resides in large-scale filaments in the form of a diffuse plasma at temperatures $T \sim 1…
A clumpy and anisotropic galaxy halo at z=1 from gravitational-arc tomography
Sebastian Lopez, Nicolas Tejos, Cedric Ledoux +6
Every star-forming galaxy has a halo of metal-enriched gas extending out to at least 100 kpc, as revealed by the absorption lines this gas imprints on the spectra of background qua…
