a b s t r a c t The ab initio quasirelativistic Hartree–Fock method developed specifically for the calculation of spectral parameters of heavy atoms and highly charged ions is used to derive transition data for a multicharged tungsten ion. The configuration interaction method is applied to include electron correlation effects. The relativistic effects are taken into account in the Breit–Pauli approximation for quasirelativistic Hartree–Fock radial orbitals. The energy level spectra, radiative lifetimes and Lande gfactors are calculated for the 4p 6 4d 2 , 4p 6 4d4f, and 4p 5 4d 3 configurations of the ion W 36+ . The transition wavelengths, spontaneous transition probabilities, oscillator strengths, and line strengths for the electric dipole, electric quadrupole, electric octupole, and magnetic dipole transitions among the levels of these configurations are tabulated.read more

Formation of GW190521 from stellar evolution: the impact of the hydrogen-rich envelope, dredge-up and $^{12}$C($α$, $γ$)$^{16}$O rate on the pair-instability black hole mass gap
Guglielmo Costa,Guglielmo Costa,Alessandro Bressan,Alessandro Bressan,Michela Mapelli,Michela Mapelli,Paola Marigo,Giuliano Iorio,Giuliano Iorio,Mario Spera +9 more
TL;DR: In this paper, the authors investigated the existence of the pair-instability mass gap in the mass spectrum of black holes and showed that the mass gap can be closed by the collapse of the residual H-rich envelope at metallicity 0.0003.

Momentum-dependent hybridization gap and dispersive in-gap state of the Kondo semiconductor SmB 6
TL;DR: In this article, the temperature-dependent three-dimensional angle-resolved photo-emission spectra of the Kondo semiconductor SmB${}_{6}$ were reported, showing that the peak intensity at the $X$ point has the same temperature dependence as the valence transition below 120 K, while that at the $\ensuremath{\Gamma}$ point is consistent with the magnetic excitation at $Q=(05,05, 05,05)$ below 30 K.

CHIANTI -- an atomic database for emission lines -- Paper XVI: Version 10, further extensions
TL;DR: The CHIANTI package as discussed by the authors provides atomic models for several helium-like ions and for all the ions of the beryllium, carbon and magnesium isoelectronic sequences that are abundant in astrophysical plasmas.

An MCMC determination of the primordial helium abundance
TL;DR: In this paper, Markov Chain Monte Carlo (MCMCMC) was applied to the large dataset recently compiled by Izotov, Thuan, & Stasinska (2007).

The theory of atomic structure and spectra
TL;DR: In this article, the Slater-Condon theory of atomic structure and spectra is combined with a coherent set of closed-form equations suitable both for computer calculations on cases of arbitrary complexity and for hand calculations for very simple cases.
