The ESO's Extremely Large Telescope Working Groups

Paolo Padovani, Michele Cirasuolo, Remco van der Burg +82

Since 2005 ESO has been working with its community and industry to develop an extremely large optical/infrared telescope. ESO's Extremely Large Telescope, or ELT for short, is a re…

Survey for Distant Solar Twins (SDST) -- III. Identification of new solar twin and solar analogue stars

Christian Lehmann, Michael T. Murphy, Fan Liu +3

The Survey for Distant Solar Twins (SDST) aims to find stars very similar to the Sun at distances 1-4 kpc, several times more distant than any currently known solar twins and analo…

MUSE Analysis of Gas around Galaxies (MAGG) -- V: Linking ionized gas traced by CIV and SiIV absorbers to Ly emitting galaxies at

Marta Galbiati, Michele Fumagalli, Matteo Fossati +5

We use 28 quasar fields with high-resolution (HIRES and UVES) spectroscopy from the MUSE Analysis of Gas Around Galaxies survey to study the connection between Ly emitters (LAEs…

A limit on variations in the fine-structure constant from spectra of nearby Sun-like stars

Michael T. Murphy, Daniel A. Berke, Fan Liu +4

The fine structure constant, , sets the strength of the electromagnetic force. The Standard Model of particle physics provides no explanation for its value, which could potentia…

Survey for Distant Solar Twins (SDST) -- II. Design, observations and data

Fan Liu, Michael T. Murphy, Christian Lehmann +5

Studies of solar twins have key impacts on the astronomical community, but only 100--200 nearby solar twins ( 1 kpc) have been reliably identified over the last few decade…

Probing Galactic variations in the fine-structure constant using solar twin stars: systematic errors

Daniel A. Berke, Michael T. Murphy, Chris Flynn +1

Sun-like stars are a new probe of variations in the fine-structure constant, , via the solar twins approach: velocity separations of close pairs of absorption lines are compared…
