Unveiling VVV/WISE Mira variables on the far side of the Galactic disk: Distances, kinematics and a new extinction law

Autor: Albarracín, Rogelio, Zoccali, M., Carvajal, J. Olivares, Rojas-Arriagada, Á., Minniti, J. H., Catelan, M., De Leo, M., Gran, F., Ramos, R. Contreras, Navarro, Á. Valenzuela, Salvo-Guajardo, C.

The structure and kinematics of the Milky Way disk are largely inferred from the solar vicinity. To gain a comprehensive understanding, it is essential to find reliable tracers in less-explored regions like the bulge and the far side of the disk. Mir

Abundances of iron-peak elements in 58 bulge spheroid stars from APOGEE

Stars presently identified in the bulge spheroid are probably very old, and their abundances can be interpreted as due to the fast chemical enrichment of the early Galactic bulge. The abundances of the iron-peak elements are important tracers of nucl

The ESO public survey VISTA Variables in the V\'ia L\'actea (VVV) surveyed the inner Galactic bulge and the adjacent southern Galactic disk from $2009-2015$. Upon its conclusion, the complementary VVV eXtended (VVVX) survey has expanded both the temp

Theia: Distilling Diverse Vision Foundation Models for Robot Learning

Autor: Shang, Jinghuan, Schmeckpeper, Karl, May, Brandon B., Minniti, Maria Vittoria, Kelestemur, Tarik, Watkins, David, Herlant, Laura

Vision-based robot policy learning, which maps visual inputs to actions, necessitates a holistic understanding of diverse visual tasks beyond single-task needs like classification or segmentation. Inspired by this, we introduce Theia, a vision founda

VVVX survey dusts off a new intermediate-age star cluster in the Milky Way disk

Autor: Garro, E. R., Minniti, D., Alonso-García, J., Fernández-Trincado, J. G., Gómez, M., Palma, T., Saito, R. K., Obasi, C.

Our primary long-term objective is to seek out additional star clusters in the poorly studied regions of the MW. The aim of this pursuit is to finalize the MG's globular and open cluster system census and to gain a comprehensive understanding of both
