An overview of HMI off-disk flare observations
Dennis Fremstad, Juan Camilo Guevara Gómez, Hugh Hudson +1
Context: White-light continuum observations of solar flares often have coronal counterparts, including the classical ``white-light prominence'' (WLP) phenomenon. Aims: Coronal emis…
The Sun at millimeter wavelengths IV. Magnetohydrodynamic waves in small-scale bright features
Juan Camilo Guevara Gómez, Shahin Jafarzadeh, Sven Wedemeyer +3
We used solar observations of a plage/enhanced network with the Atacama Large Millimeter/sub-millimeter Array (ALMA) in Band 3 and Band 6 together with synthetic continuum maps fro…
Propagation of transverse waves in the solar chromosphere probed at different heights with ALMA sub-bands
Juan Camilo Guevara Gómez, Shahin Jafarzadeh, Sven Wedemeyer +1
The Atacama Large Millimeter/sub-millimeter Array (ALMA) has provided us with an excellent diagnostic tool for studies of the dynamics of the Solar chromosphere, albeit through a s…
The Solar ALMA Science Archive (SALSA)
Vasco M. J. Henriques, Shahin Jafarzadeh, Juan Camilo Guevara Gómez +5
In December 2016, the Atacama Large Millimeter/submillimeter Array (ALMA) carried out the first regular observations of the Sun. These early observations and the reduction of the r…
Analysis of the directionality on periodic materials
Nicolás Guarín-Zapata, Camilo Valencia, Juan Gómez
There is an increasing interest in the study of metamaterials and periodic materials across disciplines. These are anisotropic and their properties present directionality. For exam…
High-frequency oscillations in small chromospheric bright features observed with ALMA
Juan Camilo Guevara Gómez, Shahin Jafarzadeh, Sven Wedemeyer +4
We report detection of oscillations in brightness temperature, size, and horizontal velocity of three small bright features in the chromosphere of a plage/enhanced-network region.…
