Context. The measurement of diffuse 21-cm radiation from the hyperfine transition of neutral hydrogen (H I signal) in different redshifts is an important tool...
The BINGO Project. III. Optical design and optimization of the focal plane
Context. The Baryon Acoustic Oscillations from Integrated Neutral Gas Observations (BINGO) telescope was designed to measure the fluctuations of the 21 cm...
The BINGO project. IV. Simulations for mission performance assessment and preliminary component separation steps
Aims: The large-scale distribution of neutral hydrogen (H I) in the Universe is luminous through its 21 cm emission. The goal of the Baryon Acoustic...
The BINGO project. V. Further steps in component separation and bispectrum analysis
Context. Observing the neutral hydrogen distribution across the Universe via redshifted 21 cm line intensity mapping constitutes a powerful probe for cosmology...
The bivariate gas-stellar mass distributions and the mass functions of early- and late-type galaxies at z {∼} 0
We report the bivariate $HI$ - and $H 2$ -stellar mass distributions of local galaxies in addition of an inventory of galaxy mass functions, MFs, for $HI$ , $H...
The black hole binary nova Scorpii 1994 (GRO J1655-40): an improved chemical analysis
Context: The chemical analysis of secondary stars of low mass X-ray binaries provides an opportunity to study the formation processes of compact objects, either...
The Black Hole Mass-Color Relations for Early- and Late-type Galaxies: Red and Blue Sequences
The tight correlations between supermassive black hole (SMBH) mass (M BH) and the properties of the host galaxy have useful implications for our understanding...
The black hole population in low-mass galaxies in large-scale cosmological simulations
Recent systematic searches for massive black holes (BHs) in local dwarf galaxies led to the discovery of a population of faint active galactic nuclei (AGNs). We...
The black hole transient Nova Scorpii 1994 (=GRO J1655-40): orbital ephemeris and optical light curve
We have measured the brightness of the optical counterpart of the black hole X-ray binary Nova Sco 1994 (GRO J1655-40) during 40 nights between 1995 May 3 and...
