Pilar Ruiz-Lapuente - Selected publications#

Tension in the void: cosmic rulers strain inhomogeneous cosmologies. Zumalacárregui, M., García-Bellido, J., Ruiz-Lapuente, P. JCAP 10, 009 (2012) [Important paper, ruling out the whole class of adiabatic Lemaître-Tolman-Bondi cosmological models proposed as an alternative to Dark Energy. Based in part on the Ph.D. work of M. Zumalacárregui, supervised by P. Ruiz-Lapuente]

No surviving evolved companions of the progenitor of SN1006. González Hernández, J.I., Ruiz-Lapuente, P., et al. Nature 489, 533 (2012) [Evidence that this supernova was most likely produced by the merging of two white dwarfs. Together with the 2004 and 2009 papers cited below, confirms the existence of two different channels to Type Ia supernova explosions]

Astrophysics: Progenitors of type Ia supernovae. Ruiz-Lapuente, P. Nature 481, 149 (2012) [Invited contribution]

Spectra and Hubble Space Telescope Light Curves of Six Type Ia Supernovae at 0.511 < z < 1.12 and the Union2 Compilation. Amanullah, R., et al., incl. Ruiz-Lapuente, P. ApJ 716, 712 (2010) [The most recent constraints on the cosmological parameters, from observations of Type Ia supernovae, obtained by the Spernova Cosmology Project (more than 550 citations in the scientific literature, to date)]

Dark Energy: Observational and Theoretical Approaches. Edit. P. Ruiz-Lapuente (Cambridge Univ. Press) (2010) [One of the very few books treating all aspects of the research on dark energy]

The Chemical Abundances of Tycho G in Supernova Remnant 1572. González Hernández, J.I., Ruiz-Lapuente, P., et al. ApJ 691, 1 (2009) [Confirmation of the discovery made in 2004]

Dark energy, gravitation and supernovae. Ruiz-Lapuente, P. Class. & Quant. Grav. 24R, 91 (2007) [Invited review]

The binary progenitor of Tycho Brahe's 1572 supernova. Ruiz-Lapuente, P., et al. Nature 431, 1069 (2004) [The only discovery, to date, of the companion star of a Type Ia supernova. Apart from being a very cited paper in the scientific literature (about 100 citations), it made big media news around the world]

Measurements of Omega and Lambda from 42 High-Redshift Supernovae. Perlmutter, S., et al., incl. Ruiz-Lapuente, P. ApJ 517, 565 (1999) [The paper for which S. Perlmutter has been awarded the Nobel Prize for Physics in 2011. Based, in part, on observations made by P. Ruiz-Lapuente at La Palma]

A possible low-mass type Ia supernova. Ruiz-Lapuente, P., et al. Nature 365, 728 (1993) [The first and very early evidence that some Type Ia supernovae are thermonuclear explosions of white dwarfs with masses below the Chandrasekhar mass (something almost universally taken for granted, nowadays)]
