On the later evolution of observationally selected protocluster candidates at

Seunghwan Lim

Recent observations have revealed numerous protocluster candidates at , yet whether these systems will eventually evolve into today's galaxy clusters remains an op…

Too many protoclusters? Reconciling the overabundance of cluster progenitors within the first billion years of the Universe

Callum Witten, Jake S. Bennett, Pascal A. Oesch +8

JWST has revealed an overabundance of apparent (`Coma'-like) cluster progenitors at that is two (300) times in excess of, and in () tension with, the number…

Think inside the box: cosmic variance and large-scale conformity of high-redshift massive galaxies in the FLAMINGO simulations

Seunghwan Lim, Sandro Tacchella, Roberto Maiolino +2

We use the highest-resolution FLAMINGO hydrodynamical simulation to quantify cosmic variance and large-scale coherence in the evolution of massive galaxies at high redshift. FLAMIN…

In-situ vs. ex-situ drivers of galaxy quenching: critical black hole mass and main sequence universality in the FLAMINGO simulation

Seunghwan Lim, Sandro Tacchella, Roberto Maiolino +2

Exploiting a large sample of 5.3 million galaxies with from the highest-resolution FLAMINGO simulation, we carry out a statistical analysis…

The abundance and nature of high-redshift quiescent galaxies from JADES spectroscopy and the FLAMINGO simulations

William M. Baker, Seunghwan Lim, Francesco D'Eugenio +20

We use NIRSpec/MSA spectroscopy and NIRCam imaging to study a sample of 18 massive (dex), central quiescent galaxies at in the GOO…

The FLAMINGO simulation view of cluster progenitors observed in the epoch of reionization with JWST

Seunghwan Lim, Sandro Tacchella, Joop Schaye +4

Motivated by the recent JWST discovery of galaxy overdensities during the Epoch of Reionzation, we examine the physical properties of high- protoclusters and their evolution usi…

GA-NIFS: The core of an extremely massive proto-cluster at the Epoch of Reionization probed with JWST/NIRSpec

Santiago Arribas, Michele Perna, Bruno Rodríguez Del Pino +24

The SPT0311-58 system resides in a massive dark matter halo at z ~ 6.9. It hosts two dusty galaxies (E and W) with a combined star formation rate of ~3500 Msun/yr. Its surrounding…
