Simulating high-speed solar wind streams from coronal holes using an L5-L1 configuration of lagrangian points
Our approach consists of three main steps. First, we perform initial predictions of velocities of HSSs using a longitudinal separation angle between each pair of probes and accounting for the distance from simulated “L5” and “L1” to the…

The S-PLUS Fornax Project (S+FP): Mapping Globular Clusters Systems within 5 Virial Radii around NGC 1399
We present the largest sample (∼13,000 candidates, ∼3000 of which are bona fide candidates) of globular cluster (GCs) candidates reported in the Fornax cluster so far. The survey is centered on the NGC 1399 galaxy, extending out to 5 virial…
