Hace 4 días · HOST NOELIA GONZÁLEZ: Desde que comenzó sus observaciones científicas en julio de 2022, Webb nos ha acercado a algunas de las primeras galaxias del universo primitivo; ha retratado el nacimiento y la muerte de estrellas lejanas. También ha observado objetos más cercanos, como planetas de nuestro sistema solar.
Hace 5 días · Fig. 5: Measurements of the SMF and its evolution with redshift in COSMOS-Web. Each panel shows the SMF in a given redshift bin, along with measurements in the literature fromWeaver et al.(2022b); ... ∼0.7 Gyrs. The most massive galaxies in COSMOS – We apply the EVS to search for the most extreme sources for their epoch, ...
Hace 3 días · Then in 2001, the 2dF Galaxy Redshift Survey gave strong evidence that the matter density is around 30% of critical. The large difference between these two supports a smooth component of dark energy making up the difference.
Hace 4 días · NIR images and NIR grism data were obtained. Our analysis of these data (Section 3) shows that the spectral features associated with the supernova at late time (∼50 days) are redshifted by several thousands of km/s compared to the redshift o.
Hace 2 días · Researchers have discovered a distant disc galaxy that has surprisingly similar characteristics to our own Milky Way, and it could change our understanding of how galaxies form.
Hace 4 días · ESA scientists today revealed the first chunk of what will be the largest-ever 3D map of the cosmos. The sparkling purplish-blue tapestry showcases data from 260 observations by the Euclid space...
