VLT/VIMOS Integral field kinematics of the Giant Low Surface Brightness galaxy ESO 323-G064
L. Coccato, R. Swaters, V. C. Rubin +2
We studied the bulge and the disk kinematic of the giant Low Surface Brightness (LSB) galaxy ESO 323-G064 in order to investigate its dynamics and its Dark Matter (DM) content. We…
High-precision wavelength calibration of astronomical spectrographs with laser frequency combs
M. T. Murphy, Th. Udem, R. Holzwarth +8
We describe a possible new technique for precise wavelength calibration of high-resolution astronomical spectrographs using femtosecond-pulsed mode-locked lasers controlled by stab…
High-Precision Measurements of Delta alpha/alpha from QSO Absorption Spectra
Sergei A. Levshakov, Paolo Molaro, Sebastian Lopez +4
Precise radial velocity measurements (delta v/c ~ 10^{-7}) of FeII lines in damped Ly-alpha systems from very high quality VLT/UVES spectra of quasars HE0515-4414 and Q1101-264 are…
Clues to the origin of metals in the Ly-alpha forest
S. Lopez, S. D'odorico, S. L. Ellison +1
We analyze the z=2 Ly-alpha and CIV forest along two adjacent lines-of-sight at high S/N and spectral resolution to assess the question of the origin of metals in the intergalactic…
Exploring the Lyman Forest with VLT/UVES
S. Cristiani, S. Bianchi, S. D'Odorico +1
A sample of 8 QSOs with 1.7 < z_em < 3.7 has been observed with VLT/UVES at a typical resolution 45000 and S/N~40-50. Thanks to the two-arm design of the spectrograph, a remarkable…
The lithium isotope ratio in the metal-poor halo star G271-162 from VLT/UVES observations
P. E. Nissen, M. Asplund, V. Hill +1
A high resolution (R = 110.000), very high S/N (>600) spectrum of the metal-poor turnoff star G271-162 has been obtained in connection with the commissioning of UVES at VLT/Kueyen.…
