In order to test the expansion of the universe and its geometry, we carry out an Alcock-Paczyński cosmological test, that is, an evaluation of the ratio of...
Alcock-Paczynski test with model-independent BAO data
Cosmological tests based on the statistical analysis of galaxy distributions usually depend on source evolution. An exception is the Alcock–Paczyński (AP) test...
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...
Alfvén wave coupled with flow-driven fluid instability in interpenetrating plasmas
The Alfvén wave is analyzed in case of one quasineutral plasma propagating with some constant speed v0 through another static quasineutral plasma. A dispersion...
Magnetohydrodynamic Alfvén waves1 have been a focus of laboratory plasma physics2 and astrophysics3 for over half a century. Their unique nature makes them...
AlH lines in the blue spectrum of Proxima Centauri
The recently computed ExoMol line lists for isotopologues of AlH are used to analyse the blue spectrum (4000-4500 Å) of Proxima Cen (M5.5 V). Comparison of the...
Aligned electromagnetic excitations of a black hole and their impact on its quantum horizon
We show that elementary aligned electromagnetic excitations of black holes, as coming from exact Kerr-Schild solutions, represent light-like beams pulses which...
Alignment determination of the Hayabusa2 laser altimeter (LIDAR)
In this study, we determined the alignment of the laser altimeter aboard Hayabusa2 with respect to the spacecraft using in-flight data. Since the laser...
All-sky angular power spectra from cleaned WISE×SuperCOSMOS galaxy number counts
Aiming to extract cosmological information from linear scales of the WISE×SuperCOSMOS photometric redshift catalog, we perform a characterization of the...
