This time we will focuss our discussion on the recently published paper on a Dark matter-free ultra faint galaxy https://arxiv.org/abs/1901.05973 (A second galaxy missing dark matter in the NGC1052 group).
We can also discuss on the previous "discovery" made by van Dokkum et al., presented last year in Nature (http://adsabs.harvard.edu/abs/2018Natur.555..629V).

Spatially-resolved analysis of the Star Formation Rate: insights on the activation and quenching mechanisms in bulges and disks

Abstract: To examine the relative role of the processes that can trigger and quench star formation on different spatial scales, it is essential to isolate the basic stellar structures that shaped galaxies (spiral arms, bars, bulges, etc.). Thus, we have combined a 2D multi-component photometric decomposition with CALIFA IFS data in a representative sample of 220 nearby galaxies. This allows us to determine the stellar mass and SFR from each of these components. Based on these parameters, the Star Formation Main Sequence of galaxies is explored. The main finding is that not only more massive galaxies but also more massive star-forming disks and earlier-type spiral disks have undergone efficient suppression of their star formation. We evaluate which mechanisms might be responsible for this quenching process. In particular, we analyze the presence of AGNs as a possible internal cause of star formation shutdown. The sSFR–M∗ relation for both disks and bulges is analyzed, finding that type-2 AGNs play a role damping the sSFR in bulges and less efficiently in disks. We emphasize the importance of the spatially-resolved analysis to provide an in-depth understanding of the processes that govern star formation.

Applying deep learning techniques to analyzing weak lensing data

Summary: Weak lensing (WL) measurements allow us to reconstruct the evolution of the matter density field, unlocking a wealth of cosmological information. As a result, many experiments such as Euclid, WFIRST or LSST will include extensive WL measurements as part of their scientific program. I will discuss our efforts to extract as much cosmological information from these upcoming datasets as possible. In particular, I will show as a proof of concept how neural networks can extract information from simulated WL maps beyond two-point statistics and some non-Gaussian observables.
