A smooth, solventless and solid state debromination of C70Br10 can be achieved in a CsI matrix with the restoration of the pristine C70 in quantitative yields. Such debromination reaction was studied with FT-IR spectroscopy and its kinetics was fitted by a pseudofirst order law, with a rate constant in the range of 3.6-5.2 x 10−5 s−1. The thermal

Understanding how gas flows into galactic centers, fuels the AGN and in turn is expelled back through feedback processes is of great importance to appreciate the role AGN play in the growth and evolution of galaxies. We use MUSE-AO optical spectra of the inner 7''. 5 × 7''. 5 of the nearby Seyfert 1 galaxy NGC 4593 to understand how gas flows in

Observations of large amounts of massive galaxies with relatively old populations found at high redshifts are challenging galaxy formation scenarios within the standard cosmology. Precise determinations of the average age of these galaxies would be useful for the discussion of this problem. Here we carry out a better constraint of the age of 200 V

We report discovering an exoplanet from following up a microlensing event alerted by Gaia. The event Gaia22dkv is toward a disk source rather than the traditional bulge microlensing fields. Our primary analysis yields a Jovian planet with at a projected orbital separation au, and the host is a ∼1.1 M ⊙ turnoff star at ∼1.3 kpc. At , the host is far

Context. Erupting magnetic flux ropes play an important role in producing solar flares, whereas fine-scale condensed coronal rain is often found in post-flare loops. However, the formation of the MFRs in the pre-flare stage and how this leads to coronal rain in a post-eruption magnetic loop is not fully understood. Aims: We explore the formation

The axion is a long-postulated boson that can simultaneously solve two crucial problems of Modern Physics: the unexpected charge and parity symmetry observed in the strong nuclear force and the enigma of dark matter. The Dark-photons and Axion- Like particles Interferometer (DALI) is a proposal for a new generation axion detector designed to probe
