The cosmic evolution of the barred galaxy population provides key information about the secular evolution of galaxies and the settling of rotationally dominated discs. We study the bar fraction in the SMACSJ0723.37323 (SMACS0723) cluster of galaxies at z = 0.39 using the Early Release Observations obtained with the NIRCam instrument mounted on the JWST telescope. We visually inspected all cluster member galaxies using the images from the NIRCam F200W filter. We classified the galaxies into ellipticals and discs and determine the presence of a bar. The cluster member selection was based on a

The first test images from its two instruments show its potential for achieving its scientific goals. These images will be used to check the instruments and to see how Euclid can be adjusted and fine tuned for best performance. The European Space Agency (ESA)’s Euclid mission, in which the Instituto de Astrofísica de Canarias (IAC) is participating, will produce the biggest and most accurate 3D map of the universe. Euclid’s two instruments VIS (VISible instrument) and NISP (Near Infrared Spectrometer and Photometer) have taken their first test images. The results indicated that this space

The first batch of data from the Dark Energy Spectroscopic Instrument is now available for researchers to mine. Taken during the experiment’s “survey validation” phase, the data include distant galaxies and quasars as well as Milky Way stars. The universe is big, and it’s getting bigger. To study dark energy, the mysterious force behind the accelerating expansion of our universe, scientists are using the Dark Energy Spectroscopic Instrument (DESI) to map more than 40 million galaxies, quasars, and stars. Today, the collaboration, which includes the Instituto de Astrofísica de Canarias (IAC)
