The bulk of the stellar growth over cosmic time is dominated by IR-luminous galaxies at cosmic noon (z = 1–2), many of which harbor a hidden active galactic nucleus (AGN). We use state-of-the-art infrared color diagnostics, combining Spitzer and[...]![]()

Dullo, Bililign T. ; Bouquin, Alexandre Y. K. ; Gil de Paz, Armando ; Knapen, Johan H. ; Gorgas García, Francisco Javier | IOP publishing ltd | 2020-07Tight correlations between supermassive black hole (SMBH) mass (M_(BH)) and the properties of the host galaxy have useful implications for our understanding of the growth of SMBHs and evolution of galaxies. Here, we present newly observed correl[...]![]()

Barrio Uña, Juan Abel ; Contreras González, José Luis ; Domínguez Díaz, Alberto ; Carreto Fidalgo, David Friedrich ; Fonseca González, Victoria ; Hoang, Kim Dinh ; López Moya, Marcos ; Nievas Rosillo, Mireia ; Peñil del Campo, Pablo ; Saha, Lab | IOP publishing ltd | 2018-08-10A neutrino with energy similar to 290 TeV, IceCube-170922A, was detected in coincidence with the BL Lac object TXS. 0506+056 during enhanced gamma-ray activity, with chance coincidence being rejected at similar to 3 sigma level. We monitored the[...]![]()

The even-even N=90 isotones with Z=60-66 are known to undergo a first order phase transition. Such a phase transition in atomic nuclei is characterized by a sudden change of the shape of the nucleus due to changes in the location of the potentia[...]![]()

K2-18 is a nearby M2.5 dwarf, located at 34 pc and hosting a transiting planet that was first discovered by the K2 mission and later confirmed with Spitzer Space Telescope observations. With a radius of similar to 2 R-circle plus and an orbital [...]![]()

Madore, Barry F. ; Gil de Paz, Armando ; Pevunova, Olga ; Thompson, Ian | IOP publishing ltd | 2007-07The object NGC 6908 was once thought to simply be a surface brightness enhancement in the eastern spiral arm of the nearby spiral galaxy NGC 6907. Based on an examination of near-infrared imaging, the object is shown to in fact be a lenticular S[...]![]()

Critical points of semiclassical expansions of solutions to the dispersionful Toda hierarchy are considered and a double scaling limit method of regularization is formulated. The analogues of the critical points characterized by the strong condi[...]![]()

Jeskel, Jan ; Rivas, Ángel ; Ahmed, Muhammad H. ; Martín-Delgado Alcántara, Miguel Ángel ; Cole, Jared H. | IOP publishing ltd | 2018-09-18The dynamics and thermal equilibrium of spin waves (magnons) in a quantum ferromagnet as well as the macroscopic magnetisation are investigated. Thermal noise due to an interaction with lattice phonons and the effects of spatial correlations in [...]![]()

Martin Martinez, Eduardo ; Garay Elizondo, Luis Javier ; León, Juan | IOP publishing ltd | 2012-11-21We analyse the evolution of the entanglement of a non-trivial initial quantum field state (which, for simplicity, has been taken to be a bipartite state made out of vacuum and the first excited state) when it undergoes a gravitational collapse. [...]![]()

Chiodo, G. ; García Herrera, Ricardo ; Calvo Fernández, Natalia ; Vaquero, J. M. ; Añel, J. A. ; Barriopedro Cepero, David ; Matthes, K. | IOP publishing ltd | 2016-03Solar variability represents a source of uncertainty in the future forcings used in climate model simulations. Current knowledge indicates that a descent of solar activity into an extended minimum state is a possible scenario. With aid of experi[...]![]()
