Visualizing the "Heartbeat" of a City with Tweets
Urbano França, Hiroki Sayama, Colin McSwiggen +2
Describing the dynamics of a city is a crucial step to both understanding the human activity in urban environments and to planning and designing cities accordingly. Here we describ…
Probing interactions within the dark matter sector via extra radiation contributions
Urbano Franca, Roberto A. Lineros, Joaquim Palacio +1
The nature of dark matter is one of the most thrilling riddles for both cosmology and particle physics nowadays. While in the typical models the dark sector is composed only by wea…
Cosmological lepton asymmetry with a nonzero mixing angle θ_{13}
Emanuele Castorina, Urbano Franca, Massimiliano Lattanzi +4
While the baryon asymmetry of the Universe is nowadays well measured by cosmological observations, the bounds on the lepton asymmetry in the form of neutrinos are still significant…
Model independent constraints on mass-varying neutrino scenarios
Urbano Franca, Massimiliano Lattanzi, Julien Lesgourgues +1
Models of dark energy in which neutrinos interact with the scalar field supposed to be responsible for the acceleration of the universe usually imply a variation of the neutrino ma…
Comment on "On curvature coupling and quintessence fine-tuning"
Urbano Franca
In this comment, we show explicitly that the phenomenological model in which the quintessence field depends linearly on the energy density of the spatial curvature can provide acce…
Dark energy, curvature, and cosmic coincidence
Urbano Franca
The fact that the energy densities of dark energy and matter are similar currently, known as the coincidence problem, is one of the main unsolved problems of cosmology. We present…
