Parallaxes of southern extremely cool objects III: 118 L \& T dwarfs
R. L. Smart, B. Bucciarelli, H. R. A. Jones +17
We present new results from the Parallaxes of Southern Extremely Cool dwarfs program to measure parallaxes, proper motions and multi-epoch photometry of L and early T dwarfs. The o…
Testing the variability of the proton-to-electron mass ratio from observations of methanol in the dark cloud core L1498
M. Daprà, C. Henkel, S. A. Levshakov +6
The dependence of the proton-to-electron mass ratio, mu, on the local matter density was investigated using methanol emission in the dense dark cloud core L1498. Towards two differ…
Multiwavelength characterisation of an ACT-selected, lensed dusty star-forming galaxy at z=2.64
G. W. Roberts-Borsani, M. J. Jiménez-Donaire, M. Daprà +19
We present \ci\,(2--1) and multi-transition CO observations of a dusty star-forming galaxy, ACT\,J2029+0120, which we spectroscopically confirm to lie at \,=\,2.64. We de…
Analysis of carbon monoxied absorption at z=2.5 to constrain variation of the proton-to-electron mass ratio
M. Daprà, P. Noterdaeme, M. Vonk +2
Absorption by carbon monoxide in the spectrum of quasar SDSS J000015.16+004833.2 is investigated in order to derive a constraint on the temporal variation of the proton-to-electron…
Constraint on a varying proton-to-electron mass ratio from H2 and HD absorption at z = 2.34
M. Daprà, M. van der Laan, M. T. Murphy +1
Molecular hydrogen absorption in the damped Lyman-alpha system at z = 2.34 towards quasar Q1232+082 is analyzed in order to derive a constraint on a possible temporal variation of…
Constraint on a cosmological variation in the proton-to-electron mass ratio from electronic CO absorption
M. Daprà, M. L. Niu, E. J. Salumbides +2
Carbon monoxide (CO) absorption in the sub-damped Lyman- absorber at redshift , toward the background quasar SDSS J123714.60+064759.5 (J1237+0647), was inve…
