Dark energy and Dark matter interaction in light of the second law of thermodynamics
Víctor H. Cárdenas, Daniela Grandón, Samuel Lepe
In the context of thermodynamics we discuss the way inevitable emerge an interaction between dark components, and in this way, provide a mechanism to understand the limits of the L…
The STRong lensing Insights into the Dark Energy Survey (STRIDES) 2016 follow-up campaign. I. Overview and classification of candidates selected by two techniques
T. Treu, A. Agnello, M. A. Baumer +79
The primary goals of the STRong lensing Insights into the Dark Energy Survey (STRIDES) collaboration are to measure the dark energy equation of state parameter and the free streami…
Constraints on barotropic dark energy models by a new phenomenological parameterization
Jaime Roman-Garza, Tomas Verdugo, Juan Magana +1
In this paper, we propose a new phenomenological two parameter parametrization of to constrain barotropic dark energy models by considering a spatially flat FRW universe, ne…
Cosmological constraints on alternative model to Chaplygin fluid revisited
A. Hernandez-Almada, Juan Magana, Miguel A. Garcia-Aspeitia +1
In this work we explore an alternative phenomenological model to Chaplygin gas proposed by H. Hova et. al., consisting on a modification of a perfect fluid, to explain the dynamics…
COSMOGRAIL XVII: Time delays for the quadruply imaged quasar PG 1115+080
V. Bonvin, J. H. H. Chan, M. Millon +24
We present time-delay estimates for the quadruply imaged quasar PG 1115+080. Our resuls are based on almost daily observations for seven months at the ESO MPIA 2.2m telescope at La…
Constraining the microlensing effect on time delays with new time-delay prediction model in measurements
Geoff C. -F. Chen, James H. H. Chan, Vivien Bonvin +14
Time-delay strong lensing provides a unique way to directly measure the Hubble constant (). The precision of the measurement depends on the uncertainties in the time…
Exploring evidence of interaction between dark energy and dark matter
Daniela Grandon, Victor H. Cardenas
In this work we use the latest observations on SNIa, , BAO, in clusters and CMBR, to constrain three models showing an explicit interaction between dark matter and…
