Caught in the web: galaxy mergers along cosmic filaments
Carolina Dulcien, Yara L. Jaffe, Jacob P. Crossett +31
Galaxy clusters grow through the accretion of galaxies from groups, filaments, and other clusters. During this process, galaxies may undergo pre-processing in lower-density environ…
SLSim: a strong lensing population simulation package
Narayan Khadka, Simon Birrer, Henry Best +45
Gravitational lensing offers unique insights into cosmology by bending light around massive objects. Strong gravitational lensing, in particular, produces magnified and often multi…
Search For a Counterpart to the Subsolar Mass Gravitational Wave Candidate S251112cm
Nicholas Vieira, Noah Franz, Bhagya Subrayan +49
The recent candidate gravitational-wave (GW) alert from a compact object merger involving at least one subsolar mass (SSM) object has prompted questions about their origins. S25111…
Homogeneity scale in the local Universe: Model-independent estimate from S-PLUS iDR6 blue galaxies
Camila Franco, Felipe Avila, Armando Bernui +8
We present a model-independent estimate of the angular homogeneity scale in the local Universe by analysing data from the Southern Photometric Local Universe Survey (S-PLUS). Two c…
The role of supercluster filaments in shaping galaxy clusters
Raúl Baier-Soto, Yara Jaffé, Alexis Finoguenov +44
In a hierarchical CDM Universe, cosmic filaments serve as the primary channels for matter accretion into galaxy clusters, influencing the shape of their dark matter halos. We in…
Targeting cluster galaxies for the 4MOST CHANCES Low-z sub-survey with photometric redshifts
Hugo Méndez-Hernández, Ciria Lima-Dias, Antonela Monachesi +54
The evolution of galaxies is shaped by both internal processes and their external environments. Galaxy clusters and their surroundings provide ideal laboratories to study these eff…
