Description
We present the CIDA-UCM-Yale (Centro de Investigaciones de Astronomía, Universidad Complutense de Madrid, and Yale University) Survey (CUYS) for Hα+[NII] 6549,6584Åemission-line galaxies (ELGs) using objective-prism spectra. The most important properties of a catalogue with 427 entries and significant subsets are analysed. The complete sample contains 183 statistically confirmed ELGs in a sky area of 151 deg2 and redshift up to 0.14. We determine the parameters of the Hα luminosity function using the Hα+[NII] flux directly measured on the ELG spectra in this sample, and the star formation rate density derived is in agreement with values reported in the literature. Finally, we study the clustering properties of local star-forming galaxies relative to quiescent ones from different perspectives. We find that ELGs avoid dense regions of quiescent galaxies and we propose a power-law expression to parametrize the relation between star formation rate density and environment volume density of ELGs.

    MUSE view of PDS 456: Kiloparsec-scale wind, extended ionized gas, and close environment
    PDS 456 is the most luminous (L bol ∼ 10 47 erg s −1) radio-quiet quasar at z < 0.3 and can be regarded as a local counterpart of the powerful quasars shining at Cosmic Noon. It hosts a strong nuclear X-ray ultra-fast (∼0.3c) outflow, and a massive and clumpy CO (3-2) molecular outflow extending up to ∼5 kpc from the nucleus. We analyzed the first

    TOI-837 b is a young Saturn-sized exoplanet with a massive 70 M<SUB>⊕</SUB> core
    We present an exhaustive photometric and spectroscopic analysis of TOI-837, a F9/G0 35 Myr young star, hosting a transiting exoplanet, TOI-837 b, with an orbital period of ~8.32 d. Utilizing data from the Transiting Exoplanet Survey Satellite and ground-based observations, we determine a planetary radius of $0.818_{-0.024}^{+0.034}$ R J for TOI-837

    Changing Look of the Optical Spectrum of the MeV Blazar PKS 0446+112 (4FGL J0449.1+1121)
    Following the high activity of the γ-ray Fermi source 4FGL J0449.1+1121 (PKS 0446+112), possibly associated with a IceCube neutrino event IC-240105A, we obtained optical spectroscopy with the Gran Telescopio Canarias of the counterpart. We detect a clear emission line at 3830 Å identified as Lyα that confirms the redshift of source at z = 2.153
