The normalized matrix perturbation method [PDF]

open access: yes, 2020
In 1926, Schrodinger supplied the theoretical basis for analyzing the time evolution of a quantum system through his famous equation that now bears his name. Soon after its advent, an intrinsic interest emerged to get exactly solvable models by using the

QUIJOTE scientific results

open access: yesAstronomy & Astrophysics
We introduce a novel approach to estimate the spectral index, βs, of polarised synchrotron emission, combining the moment expansion of Cosmic Microwave Background foregrounds and the constrained Internal Linear Combination method.

The new HI supershell GS263-02+45 and the OB Association Bochum 7: close relatives? [PDF]

open access: yes, 2020
Neutral hydrogen (HI) supershells are usually identified, in a given velocity range, as a brightness temperature minimum in the HI distribution that is surrounded by walls of HI emission. McClure-Griffiths et al.

QUIJOTE-TFGI polarization calibration

open access: yesAstronomy & Astrophysics
Context. Polarization measurements in the 30–40 GHz range are essential to improving our understanding of Galactic synchrotron radiation and potential anomalous microwave emissions, and obtaining such measurements will ultimately aid in detecting ...

Local mixing length theory with compositional effects: First application to asymptotic giant branch evolution

open access: yesAstronomy & Astrophysics
Context. During the evolution of stars on the asymptotic giant branch (AGB), thermal pulses lead to the formation of strongly stratified layers in the outer regions of the CO core, which might lead to inversions in the chemical gradient.
