Description
Redshift observations of 30 clusters in the direction of the Sextans-Leo supercluster candidate are reported. The observations are part of a program which involves mapping the universe's large-scale structure, and include North Galactic Cap Abell clusters, Abell clusters that have only been partially observed, and unmeasured poor Zwicky clusters. Three large superclusters are identified in the region which surround an apparent void that is open on one side towards the galaxy void in Bootes. The minimum dimensions of the void are given, and one of the superclusters is identified based on it resemblance to Coma/A1367. The emptiness of the Bootes void and the void of Bahcall and Soneira (1982) are redefined by the positions determined for five clusters observed in other portions of the northern cap. Additionally, some galaxies appear to be within the bounds of the Sextans-Leo void.

    Discovery and Characterization of an Eccentric, Warm Saturn Transiting the Solar Analog TOI-4994
    We present the detection and characterization of TOI-4994b (TIC 277128619b), a warm Saturn-sized planet discovered by the NASA Transiting Exoplanet Survey Satellite. TOI-4994b transits a G-type star (V = 12.6 mag) with a mass, radius, and effective temperature of M ⋆ = 1.00 5 ‑ 0.061 + 0.064 M ⊙ , R ⋆ = 1.05 5 ‑ 0.037 + 0.040 R ⊙ , and T eff = 5640

    Hyperons during proto-neutron star deleptonization and the emission of dark flavoured particles
    Complementary to high-energy experimental efforts, indirect astrophysical searches of particles beyond the standard model have long been pursued. The present article follows the latter approach and considers, for the first time, the self-consistent treatment of the energy losses from dark flavoured particles produced in the decay of hyperons during

    ALESS-JWST: Joint (Sub)kiloparsec JWST and ALMA Imaging of z ~ 3 Submillimeter Galaxies Reveals Heavily Obscured Bulge Formation Events
    We present JWST NIRCam imaging targeting 13 z ~ 3 infrared-luminous (L IR ∼ 5 × 10 12L ⊙) galaxies from the ALESS survey with uniquely deep, high-resolution (0 . ″ 08–0 . ″ 16) Atacama Large Millimeter/submillimeter Array 870 μm imaging. The 2.0–4.4 μm (observed frame) NIRCam imaging reveals the rest-frame near-infrared stellar emission in these
