We present the low-resolution transmission spectra of the puffy hot Jupiter HAT-P-65b (0.53 M Jup, 1.89 R Jup, T eq = 1930 K), based on two transits observed using the OSIRIS spectrograph on the 10.4 m Gran Telescopio CANARIAS. The transmission spectra of the two nights are consistent, covering the wavelength range 517-938 nm and consisting of

Anomalous Microwave Emission (AME) is a significant component of Galactic diffuse emission in the frequency range 10- $60\, \mathrm{GHz}$ and a new window into the properties of sub-nanometre-sized grains in the interstellar medium. We investigate the morphology of AME in the ≍10 ○ diameter λ Orionis ring by combining intensity data from the

We propose the use of angular fluctuations in the galaxy redshift field as a new way to extract cosmological information in the Universe. This new probe $\delta z (\hat{\mathbf {n}})$ consists of the statistics of sky maps built by projecting redshifts under a Gaussian window of width σ z centred upon a redshift z obs, and weighted by the galaxy

El segundo catálogo Planck de fuentes Sunyaev-Zeldovich (SZ), PSZ2 en lo sucesivo, representa la mayor muestra de cumulos de galaxias seleccionados por su señal SZ cubriendo todo el cielo. En el momento de su publicación, el 21% de estos objetos no tenía una contrapartida conocida en otras longitudes de onda. Usando telescopios de los

The cross-correlation between the cosmic microwave background (CMB) fields and matter tracers carries important cosmological information. In this paper, we forecast by a signal-to-noise ratio analysis the information contained in the cross-correlation of the CMB anisotropy fields with source counts for future cosmological observations and its

Context. Many galaxies host pronounced circumnuclear starbursts, fuelled by infalling gas. Such activity is expected to drive the secular evolution of the nucleus and generate super winds which enrich the interstellar and intergalactic medium. Moreover, given the intense radiation fields and extreme gas and cosmic ray densities present within such
