Microlensing at Cosmological Distances: Event Rate Predictions in the Warhol Arc of MACS 0416
J. M. Palencia, J. M. Diego, L. Dai +13
Highly magnified stars ( 100) are now outinely identified as transient events at cosmological distances thanks to microlensing by intra-cluster stars near the critical curve…

The cold interstellar medium of a normal sub- galaxy at the end of reionization
F. Valentino, S. Fujimoto, C. Giménez-Arteaga +21
We present the results of a ~60-hr observational campaign with ALMA targeting a spectroscopically confirmed and lensed sub- galaxy at z=6.07, identified during the ALMA Le…

Primordial Rotating Disk Composed of 15 Dense Star-Forming Clumps at Cosmic Dawn
S. Fujimoto, M. Ouchi, K. Kohno +43
Early galaxy formation, initiated by the dark matter and gas assembly, evolves through frequent mergers and feedback processes into dynamically hot, chaotic structures. In contrast…
