We present MOLPOP-CEP, a universal line transfer code that allows the exact calculation of multi-level line emission from a slab with variable physical conditions for any arbitrary atom or molecule for which atomic data exist. The code includes error control to achieve any desired level of accuracy, providing full confidence in its results

We investigated the infrared (IR) dust emission from PN IC 418, using a detailed model controlled by a previous determination of the stellar properties and the characteristics of the photoionized nebula, keeping as free parameters the dust types, amounts, and distributions relative to the distance of the central star. The model includes the ionized

Most of the V-types that are known are located in the inner main belt and are members of the Vesta collisional family. The analysis of the photometric and spectroscopic properties of asteroids inside and outside the Vesta family, including V-types in the middle and outer main belt, can answer questions about the existence of differentiated bodies

We use Atacama Large Millimetre Array and Jansky Very Large Array observations of the galaxy cluster Cl J1449+0856 at z = 1.99, in order to study how dust-obscured star formation, interstellar medium content, and active galactic nuclei activity are linked to environment and galaxy interactions during the crucial phase of high-z cluster assembly. We

A measurement is presented of the Z/γ ^{*} → τ τ cross section in {pp} collisions at √{s} = 13 TeV, using data recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 2.3 fb^{-1}. The product of the inclusive cross section and branching fraction is measured to be σ ( {pp} → Z/γ ^{*} {+X}) B(Z/γ ^{*} → τ τ ) = 1848 ±

Many galaxies host pronounced (circum)nuclear starbursts, fuelled by infalling gas. Such activity drives the secular evolution of the nucleus and may also generate super winds which enrich the interstellar and intergalactic medium. Given the intense radiation fields and extreme gas densities present within these nuclear regions, star formation may
