Tidal locking as a negative feedback on Earth-like planetary dynamos: Consequences for magnetic shielding and habitability
J. P. Hidalgo, D. R. G Schleicher
We investigate how tidal locking affects the magnetic field generation and magnetospheric protection of Earth-like planets orbiting the habitable zone of M dwarfs. While the role o…
Little Red Dot progenitors from Compact Starbursts: A Natural Path to Early AGN Formation
MatÃas Liempi, Muhammad A. Latif, Dominik R. G. Schleicher
The recent discovery of Little Red Dots (LRDs) by the James Webb Space Telescope has challenged traditional models of early galaxy and black hole co-evolution. The nature of these…
Formation of intermediate-mass black holes in young massive clusters detected with JWST: analytic mass estimates
Viola Bocchi, MatÃas Liempi, Dominik R. G. Schleicher
The James Webb Space Telescope (JWST) has revealed a population of dense stellar systems at high redshift, including the "Cosmic Gems" arc () and the "Firefly Sparkle"…
Massive star clusters detected by JWST as natural birth places to form intermediate-mass black holes
Dominik R. G. Schleicher, MatÃas Liempi, Mirek Giersz +11
The James Webb Space Telescope (JWST) has detected, through gravitational lensing, several young massive star clusters (YMCs), which are considered as relevant building blocks of h…
Constraints on dynamically-formed massive black holes in Little Red Dots from X-ray non-detections
M. Liempi, D. R. G. Schleicher, M. A. Latif +4
The existence of massive, compact galaxies (Little Red Dots, LRDs) at challenges early structure formation models, suggesting rapid stellar and black hole (BH) assembly.…
Efficient black hole seed formation in low metallicity and dense stellar clusters with implications for JWST sources
M. C. Vergara, A. Askar, F. Flammini Dotti +7
Recent observations with the James Webb Space Telescope (JWST) reveal young massive clusters (YMCs) as key building blocks of early galaxies. They are not only important constituen…
