Extragalactic Planetary Nebulae (xPNe). Determining Distances out to 100 Mpc and the Renaissance of the PN Luminosity Function Method
Magda Arnaboldi, Ortwin Gerhard, Martin Roth +9
The discrepancy of the Hubble parameter H0 as measured from the cosmic microwave background versus that found from traditional distance ladder measurements has produced considerabl…
Extragalactic planetary nebulae -- tracers of kinematics and stellar populations out to 100 Mpc
Johanna Hartke, Magda Arnaboldi, Claudia Pulsoni +11
Extragalactic planetary nebulae (xPNe) in galaxies beyond the Local Universe serve as discrete tracers for studying the element abundances and kinematics of galaxies covering a wid…
Towards Precision Cosmology With Improved PNLF Distances Using VLT-MUSE. III. Impact of Stellar Populations in Early-Type Galaxy
Azlizan A. Soemitro, Lucas M. Valenzuela, Martin M. Roth +5
Distance measurements using the planetary nebula luminosity function (PNLF) rely on the bright-end power-law cut-off magnitude (), which is defined by a number of the [OIII]$\…
qCMOS detectors and the case of hypothetical primordial black holes in the solar system, near earth objects, transients, and other high cadence observations
Martin M. Roth
Recent progress with CMOS detector development has opened new parameter space for high cadence time resolved imaging of transients and fast proper motion solar system objects. Usin…
The Blue Multi Unit Spectroscopic Explorer (BlueMUSE) on the VLT: science drivers and overview of instrument design
Johan Richard, Rémi Giroud, Florence Laurent +47
BlueMUSE is a blue-optimised, medium spectral resolution, panoramic integral field spectrograph under development for the Very Large Telescope (VLT). With an optimised transmission…
The Wide-field Spectroscopic Telescope (WST) Science White Paper
Vincenzo Mainieri, Richard I. Anderson, Jarle Brinchmann +214
The Wide-field Spectroscopic Telescope (WST) is proposed as a new facility dedicated to the efficient delivery of spectroscopic surveys. This white paper summarises the initial con…
Scientific Impact of novel Instrumentation: the Case of MUSE
Martin M. Roth
In the process of transforming science cases into a viable and affordable design for a novel instrument, there is the problem of how to gauge their scientific impact, especially wh…
Integral Field Spectroscopy: a disruptive innovation for observations of Planetary Nebulae and the PNLF
Martin M. Roth, George Jacoby, Robin Ciardullo +3
A quarter of a century has passed since the observing technique of integral field spectroscopy (IFS) was first applied to planetary nebulae (PNe). Progress after the early experime…
Precision spectrophotometry for PNLF distances: the case of NGC 300
Azlizan A. Soemitro, Martin M. Roth, Peter M. Weilbacher +5
The Multi-Unit Spectroscopic Explorer (MUSE) has enabled a renaissance of the planetary nebula luminosity function (PNLF) as a standard candle. In the case of NGC 300, we learned t…
Towards Precision Cosmology With Improved PNLF Distances Using VLT-MUSE II. A Test Sample from Archival Data
George H. Jacoby, Robin Ciardullo, Martin M. Roth +2
Thanks to the MUSE integral field spectrograph on the VLT, extragalactic distance measurements with the [O III] 5007 A planetary nebula luminosity function (PNLF) are now possible…
The MUSE-Faint survey. IV. Dissecting Leo T, a gas-rich relic with recent star formation
Daniel Vaz, Jarle Brinchmann, Sebastiaan L. Zoutendijk +6
Leo T () is both the faintest and the least massive galaxy known to contain neutral gas and to display signs of recent star formation. We analyse photometry and stellar…
The E-ELT Multi-Object Spectrograph: latest news from MOSAIC
F. Hammer, S. Morris, L. Kaper +9
There are 8000 galaxies, including 1600 at z larger than 1.6, which could be simultaneously observed in an E-ELT field of view of 40 sq. arcmin. A considerable fraction of astrophy…
