PublicationUpper limits on gravitational wave bursts in LIGO's second science run
We perform a search for gravitational wave bursts using data from the second science run of the LIGO detectors, using a method based on a wavelet time-frequency...

PublicationUpper Limits to the Magnetic Field in Central Stars of Planetary Nebulae
More than about 20 central stars of planetary nebulae (CSPNs) have been observed spectropolarimetrically, yet no clear, unambiguous signal of the presence of a...

PublicationVariation in sunspot properties between 1999 and 2014
Aims: We study the variation in the magnetic field strength, area, and continuum intensity of umbrae in solar cycles 23 and 24. Methods: We analyzed a sample of...

PublicationVector magnetic field map at the photospheric level below and around a solar filament (neutral line)
We present a vector magnetic field map obtained on 7 December 2003, below and around a filament located not so far from the active region NOAA 517, whose one...

PublicationVector magnetic fields of emerging solar flux. I. Properties at the site of emergence
Several small emerging bipolar regions have been observed with the Advanced Stokes Polarimeter (ASP), including extensive time series measurements of one small...

PublicationVelocity fields below the magnetic canopy of solar flux tubes: evidence for high-speed downflows?
It is well-established that velocities in the immediate surroundings of solar magnetic elements produce an asymmetry in the Stokes V profiles emerging from the...

PublicationVFISV: Very Fast Inversion of the Stokes Vector for the Helioseismic and Magnetic Imager
In this paper we describe in detail the implementation and main properties of a new inversion code for the polarized radiative transfer equation (VFISV: Very...

PublicationWave heating of the solar atmosphere
Magnetic waves are a relevant component in the dynamics of the solar atmosphere. Their significance has increased because of their potential as a remote...
