Merger remnant in TXS 1033+026 - I: and HI 21-cm observations suggest counter-rotating gas
J. N. H. S. Aditya, Hyein Yoon, L. G. Dahmer-Hahn +5
We conducted eMERLIN and Gemini integral field unit (IFU) observations towards TXS 1033+026, a post-merger ultraluminous infrared galaxy, to study the radio continuum and …
Detection of metal absorption lines in quasar spectra: a neural network approach using U-Net
Elena Sofia Mangola, Francesco Pistis, Michele Fumagalli +7
Current and future large spectroscopic surveys are significantly enhancing the volume and resolution of quasar spectra that are observed, which requires the creation of efficient a…
Cosmic web Ly emission in a sample of overdense regions
Davide Tornotti, Michele Fumagalli, Matteo Fossati +7
We present a complete and homogeneous analysis of the Ly emission properties of the cosmic web at as a function of the overdensity of Ly emitters (L…
The Multiphase CGM in the Epoch of Reionization: CII and CIV absorbers around [OIII] Emitters
C. Piscitelli, V. D'Odorico, M. Galbiati +17
We investigate the multiphase circumgalactic medium (CGM) during the Epoch of Reionization (EoR, ) by cross-correlating cool- CII and warm-ionized CIV absorption systems with…
The environmental dependence of the circumgalactic medium in a high-resolution cosmological simulation
Georg Herzog, Rajeshwari Dutta, Michele Fumagalli
There is increasing evidence from observations that the circumgalactic medium (CGM) of galaxies depends on the large-scale structure in which they are embedded. When probing the CG…
Forecast for the detectability of patchy hydrogen reionization in WEAVE-QSO measurements of the Lyman- forest power spectrum at redshift
Ke Ma, James S. Bolton, Vid Iršič +9
We present the first detailed forecasts for the detectability of patchy hydrogen reionization in the one-dimensional Ly forest power spectrum to be measured by the WEAVE-QSO sur…
The MUSE Ultra Deep Field (MUDF) VIII. The cool gas distribution surrounding galaxies at redshifts z ~ 0.5-2
Edoardo Santo, Michele Fumagalli, Seok-Jun Chang +5
We use deep MUSE data from the MUDF survey to investigate the cool gas around galaxies at redshifts 0.5 < z < 2. We constructed two samples: one sample for a down-the-barrel analys…
A quiescent galaxy in a gas-rich cosmic web node at z~3
Weichen Wang, Sebastiano Cantalupo, Marta Galbiati +11
Recent JWST observations have unveiled a large number of quiescent galaxies at , bringing potential challenges to current galaxy formation models. Since star formation i…
Automated quasar continuum estimation using neural networks: a comparative study of deep-learning architectures
Francesco Pistis, Michele Fumagalli, Matteo Fossati +13
Context. Ongoing and upcoming large spectroscopic surveys are drastically increasing the number of observed quasar spectra, requiring the development of fast and accurate automated…
Modeling Mg II resonance doublet spectra from galaxy haloes at z 1
Seok-Jun Chang, Rajeshwari Dutta, Max Gronke +3
We investigate the properties of cold gas at around star-forming galaxies at using Mg II spectra through radiative transfer modeling. We utilize a comprehen…
The MUSE Ultra Deep Field: A 5 Mpc stretch of the z 4 cosmic web revealed in emission
Davide Tornotti, Michele Fumagalli, Matteo Fossati +7
We detect Ly emission from a ~5 Mpc-long (comoving) portion of the cosmic web hosting an overdensity () of 19 Ly emitters (LAEs) at within the MUSE…
Metal line emission around z<1 galaxies
Rajeshwari Dutta, Michele Fumagalli, Matteo Fossati +7
We characterize, for the first time, the average extended emission in multiple lines ([OII], [OIII], and Hbeta) around a statistical sample of 560 galaxies at z~0.25-0.85. By stack…
