We present a comprehensive analysis of the evolution of the morphological and structural properties of a large sample of galaxies at z = 3-9 using early James Webb Space Telescope (JWST) CEERS NIRCam observations. Our sample consists of 850 galaxies at z > 3 detected in both Hubble Space Telescope (HST)/WFC3 and CEERS JWST/NIRCam images, enabling a

We report on the host properties of five X-ray-luminous active galactic nuclei (AGN) identified at 3 < z < 5 in the first epoch of imaging from the Cosmic Evolution Early Release Science Survey. Each galaxy has been imaged with the JWST Near-Infrared Camera, which provides rest-frame optical morphologies at these redshifts. We also derive stellar

We present an investigation into the first 500 Myr of galaxy evolution from the Cosmic Evolution Early Release Science (CEERS) survey. CEERS, one of 13 JWST ERS programs, targets galaxy formation from z ~ 0.5 to >10 using several imaging and spectroscopic modes. We make use of the first epoch of CEERS NIRCam imaging, spanning 35.5 arcmin 2, to

According to the standard cosmological model, structure formation occurs in a bottom up fashion, where small galaxies are formed first while bigger systems grow by continuous aggregation of smaller ones. Both observations and theoretical predictions of the galaxy mass function agree on the fact that dwarfs are the most numerous galaxies in the

This book is a comprehensive reference on ancient Egyptian astronomy, one of the most important topics in historical astronomy. Written by two recognized specialists—one an astronomer trained in Egyptology and the other an Egyptologist trained in astronomy—it synthesizes and analyses the international body of research surrounding this ancient

A lo largo de la historia de la humanidad, las distintas culturas incorporaron cuerpos y fenómenos celestes a su folclore, dando cuenta de su interés y fascinación por el firmamento. En la actualidad, incluso cuando la observación de los movimientos de los astros no es necesaria en nuestro día a día para la ubicación en el tiempo y en el espacio
