Resolving star-forming clumps in a z 2 lensed galaxy: a pixelated Bayesian approach
Soniya Sharma, Johan Richard, Tiantian Yuan +5
We present a pixelized source reconstruction method applied on Integral Field Spectroscopic (IFS) observations of gravitationally lensed galaxies. We demonstrate the effectiveness…
Probing 3D Structure with a Large MUSE Mosaic: Extending the Mass Model of Frontier Field Abell 370
David J. Lagattuta, Johan Richard, Franz E. Bauer +12
We present an updated strong-lensing analysis of the massive cluster Abell 370 (A370), continuing the work first presented in Lagattuta et al. (2017). In this new analysis, we take…
High Resolution spatial analysis of a z 2 lensed galaxy using adaptive coadded source-plane reconstruction
Soniya Sharma, Johan Richard, Tiantian Yuan +5
We present spatially resolved analysis of a lensed galaxy, SDSS1958+5950 at , from the Cambridge Sloan Survey of Wide Arcs in the Sky (CASSOWARY). We use our new high re…
First gas-phase metallicity gradients of galaxies with MUSE
David Carton, Jarle Brinchmann, Thierry Contini +8
Galaxies at low-redshift typically possess negative gas-phase metallicity gradients (centres more metal-rich than their outskirts). Whereas, it is not uncommon to observe positive…
Inferring gas-phase metallicity gradients of galaxies at the seeing limit: A forward modelling approach
David Carton, Jarle Brinchmann, Maryam Shirazi +7
We present a method to recover the gas-phase metallicity gradients from integral field spectroscopic (IFS) observations of barely resolved galaxies. We take a forward modelling app…
Lens Modeling Abell 370: Crowning the Final Frontier Field with MUSE
David J. Lagattuta, Johan Richard, Benjamin Clément +8
We present a strong lensing analysis on the massive cluster Abell 370 (A370; z = 0.375), using a combination of deep multi-band Hubble Space Telescope (HST) imaging and Multi-Unit…
The Astropy Problem
Demitri Muna, Michael Alexander, Alice Allen +151
The Astropy Project (http://astropy.org) is, in its own words, "a community effort to develop a single core package for Astronomy in Python and foster interoperability between Pyth…
MUSE observations of the lensing cluster Abell 1689
D. Bina, R. Pelló, J. Richard +14
We present the results obtained with MUSE on the core of the lensing cluster A1689. Integral-field observations with MUSE provide a unique view of the central region, allowing us t…
A young star-forming galaxy at z = 3.5 with an extended Ly\, halo seen with MUSE
Vera Patrício, Johan Richard, Anne Verhamme +12
Spatially resolved studies of high redshift galaxies, an essential insight into galaxy formation processes, have been mostly limited to stacking or unusually bright objects. We pre…
Extended Lyman alpha haloes around individual high-redshift galaxies revealed by MUSE
L. Wisotzki, R. Bacon, J. Blaizot +22
We report the detection of extended Ly alpha emission around individual star-forming galaxies at redshifts z = 3-6 in an ultradeep exposure of the Hubble Deep Field South obtained…
