We explore the capability of measuring lensing signals in LiteBIRD full-sky polarization maps. With a 30 arcmin beam width and an impressively low polarization noise of 2.16 μK-arcmin, LiteBIRD will be able to measure the full-sky polarization of the cosmic microwave background (CMB) very precisely. This unique sensitivity also enables the

A bright (m F150W,AB = 24 mag), z = 1.95 supernova (SN) candidate was discovered in JWST/NIRCam imaging acquired on 2023 November 17. The SN is quintuply imaged as a result of strong gravitational lensing by a foreground galaxy cluster, detected in three locations, and remarkably is the second lensed SN found in the same host galaxy. The previous

This is bug-fix release. The main user-visible changes is that npdim= option of dynesty is removed. Also because of the code change, you will not be able to resume previous dynesty runs from earlier (

It is broadly accepted that CO is a reliable tracer of H2 in massive IR (L IR ≳ 10 9 L ⊙) galaxies, and that there are clear correlations between L IR and L' CO that are qualitatively independent of environment and even redshift. We present two tales on the search for 12CO emission from dusty star-forming galaxies in both field (Lockman Hole, z < 0

Las galaxias enanas son cruciales para entender la formación y la evolución galáctica. En el marco del modelo cosmológico más ampliamente aceptado en la actualidad, CDM, las enanas serían las primeras galaxias en formarse y las estructuras más grandes se habrían ido construyendo a base de fusiones. Las galaxias enanas que se pueden observar hoy en

The INSPIRE project has built the largest sample of ultra-compact massive galaxies (UCMGs) at 0.1 < z < 0.4 and obtained their star formation histories (SFHs). Due to their preserved very old stellar populations, relics are the perfect systems to constrain the earliest epochs of mass assembly in the Universe and the formation of massive early-type
