Modeling the intrinsic alignment (IA) of galaxies poses a challenge to weak lensing analyses. The Dark Energy Survey is expected to be less impacted by IA when limited to blue, star-forming galaxies. The cosmological parameter constraints from this b

Discovery of two cyano derivatives of acenaphthylene (C$_{12}$H$_8$) in TMC-1 with the QUIJOTE line survey

Autor: Cernicharo, J., Cabezas, C., Fuentetaja, R., Agúndez, M., Tercero, B., Janeiro, J., Juanes, M., Kaiser, R. I., Endo, Y., Steber, A. L., Pérez, D., Pérez, C., Lesarri, A., Marcelino, N., de Vicente, P.

We report the discovery in TMC-1 of two cyano derivatives of the PAH acenaphthylene (C$_{12}$H$_8$). We have found two series of lines with the QUIJOTE line survey that we assign to 1-C$_{12}$H$_7$CN and 5-C$_{12}$H$_7$CN. For the 1-isomer, we have d

Statistics that capture the directional dependence of the baryon distribution in the cosmic web enable unique tests of cosmology and astrophysical feedback. We use constrained oriented stacking of thermal Sunyaev-Zel'dovich (tSZ) maps to measure the

We present photometric redshifts for 1 341 559 galaxies from the Physics of the Accelerating Universe Survey (PAUS) over 50.38 ${\rm deg}^{2}$ of sky to $i_{\rm AB}=23$. Redshift estimation is performed using DEEPz, a deep-learning photometric redshi
