Tracing the relic nature of compact galaxies through their globular cluster systems

Micheli T. Moura, Ana L. Chies-Santos, Cristina Furlanetto +6

We investigate the synthetic model of globular cluster (GC) systems of 17 compact massive galaxies (CMGs) from the Illustris TNG100 simulation to explore their connection with mass…

ILLUSTRating red nugget assembly through observations and simulations

Micheli T. Moura, Anna Ferré-Mateu, Ana L. Chies-Santos +2

The properties of massive and compact early-type galaxies provide important constraints on early galaxy formation. Among these, massive relic galaxies, characterized by old stellar…

Blowing Star Formation Away in AGN Hosts (BAH) -- III. Serendipitous discovery of a star-forming galaxy lensed by the galactic bulge of CGCG 012-070 using JWST NIRSpec

Rogemar A. Riffel, Carlos R. Melo-Carneiro, Gabriel Luan Souza-Oliveira +10

We report the detection of a gravitationally lensed galaxy by the nearby spiral galaxy CGCG 012-070 () using Integral Field Unit (IFU) observations with the Near-Infrare…

Unveiling a 36 Billion Solar Mass Black Hole at the Centre of the Cosmic Horseshoe Gravitational Lens

Carlos R. Melo-Carneiro, Thomas E. Collett, Lindsay J. Oldham +4

Supermassive black holes (SMBHs) are found at the centre of every massive galaxy, with their masses tightly connected to their host galaxies through a co-evolution over cosmic time…

Systematics in ETG Mass Profile Modelling: Strong Lensing & Stellar Dynamics

Carlos R. Melo-Carneiro, Cristina Furlanetto, Ana L. Chies-Santos

Strong gravitational lensing and stellar dynamics are independent and powerful methods to probe the total gravitational potential of galaxies, and thus, their total mass profile. H…

Low surface brightness dwarf galaxies and their globular cluster populations around the low-density environment of our closest S0 NGC3115

Marco A. Canossa-Gosteinski, Ana L. Chies-Santos, Cristina Furlanetto +12

Understanding faint dwarf galaxies is fundamental to the development of a robust theory of galaxy formation on small scales. Since the discovery of a population of ultra diffuse ga…
