We study the presence of low intensity high velocity components, which we have termed wing features in the integrated Hα emission line profiles of the H II...
Expectations of the Size Evolution of Massive Galaxies at 3 ≤ z ≤ 6 from the TNG50 Simulation: The CEERS/JWST View
We present a catalog of about 25,000 images of massive (M ⋆ ≥ 10 9 M ⊙) galaxies at redshifts 3 ≤ z ≤ 6 from the TNG50 cosmological simulation, tailored for...
Expected Number of Massive Galaxy Relics in the Present Day Universe
The number of present day massive galaxies that have survived untouched since their formation at high-z is an important observational constraint to the...
Explaining the chemical trajectories of accreted and in-situ halo stars of the Milky Way
The Milky Way underwent its last significant merger ten billion years ago, when the Gaia-Enceladus-Sausage (GES) was accreted. Accreted GES stars and progenitor...
Explaining the Mysterious Age Gap of Globular Clusters in the Large Magellanic Cloud
The Large Magellanic Cloud (LMC) has a unique cluster formation history in that nearly all of its globular clusters were formed either ~13 Gyr ago or less than...
Exploring a new definition of the green valley and its implications
The distribution of galaxies on a colour-magnitude diagram reveals a bimodality, featuring a passively evolving red sequence and a star-forming blue cloud. The...
Exploring the contamination of the DES-Y1 cluster sample with SPT-SZ selected clusters
We perform a cross validation of the cluster catalogue selected by the red-sequence Matched-filter Probabilistic Percolation algorithm (redMaPPer) in Dark...
Exploring the correlation between dark matter, intracluster light, and globular cluster distribution in SMACS0723
We present a free-form model of SMACS0723, the first cluster observed with JWST. This model does not make any strong assumptions on the distribution of mass...
Exploring the Evolutionary Paths of the Most Massive Galaxies since z ~ 2
We use Spitzer MIPS data from the FIDEL Legacy Project in the extended Groth strip to analyze the stellar mass assembly of massive (M>1011 Msolar) galaxies at z...
