Millimetre Observations of Maser-Emitting Planetary Nebulae
Boumis, Panayotis; Ramos-Larios, Gerardo; Miranda, Luis F. +7 more
Observations in the millimetre bands of maser-emitting planetary nebulae (PNe) are crucial to study their circumstellar molecular gas at the beginning of the PN phase. Maser-emitting PNe are in the earliest phases of PN formation; therefore, these sources are key objects to study the molecular content during the early evolution of PNe. These circu…
On Low Hubble Expansion Rate from Planck Data Anomalies
Capistrano, Abraão J. S.; Cabral, Luís A.; Marão, José A. P. F. +1 more
From the linear perturbations of Nash–Greene fluctuations of a background metric, we obtain profiles of Hubble function evolution H(z) and fσ8(z) measurements as compared with the ΛCDM results at intermediate redshifts 0.1<z<1. For parameter estimation, we use joint data from Planck Cosmic Microwave Background (CMB) likelihoods of CMB temper…
New Window on the Radio Emission from Galaxies, Clusters and Cosmic Web—Conference Summary
Venturi, Tiziana; Loi, Francesca
This manuscript summarizes the contributions presented and discussed during the conference "A new window on radio galaxies, clusters and cosmic web: current status and new challenges". The meeting was held online in March 2021. The works presented during the conference have been published in this associated Special Issue. Here, we outline the scie…
