The Planetary Nebula Luminosity Function [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractAlthough the method has no theoretical explanation, the [Oiii]λ5007Å planetary nebula luminosity function (PNLF) is an extremely valuable tool for obtaining accurate (< 10%) extragalactic distances out to ~ 18 Mpc. Because the PNLF works in large galaxies of all Hubble types, it is one of the best tools we have for cross-checking the results

Frontiers in Astronomy and Space SciencesFor decades, the theoretical understanding of planetary nebulae (PNe) has remained in tension with the observed universal bright-end cutoff of the PN luminosity function (PNLF).

The Luminosity Function of M3 [PDF]
The Astrophysical Journal, 1999 We present a high precision, large sample luminosity function (LF) for the Galactic globular cluster M3. With a combination of ground based and Hubble Space Telescope data we cover the entire radial extent of the cluster. The observed LF is well fit by canonical standard stellar models from the red giant branch (RGB) tip to below the main sequence ...

The Astrophysical Journal Letters, 2023 Tidal disruption events (TDEs), in which a star is destroyed by the gravitational field of a supermassive black hole (SMBH), are being observed at a high rate owing to the advanced state of survey science.

Beyond the Galaxy Luminosity Function [PDF]
Publications of the Astronomical Society of Australia, 2004 AbstractWith the advent of large-scale surveys (i.e. Legacy Surveys) it is now possible to start looking beyond the galaxy luminosity function (LF) to more detailed statistical representations of the galaxy population, i.e multivariate distributions.

On the Number of Galaxies at High Redshift
Galaxies, 2015 The number of galaxies at a given flux as a function of the redshift, z, is derived when the z-distance relation is non-standard. In order to compare different models, the same formalism is also applied to the standard cosmology.

The luminosity of the unseen: luminosity function in dark sirens
Monthly Notices of the Royal Astronomical SocietyABSTRACT Gravitational waves (GWs) offer a novel avenue for probing the Universe. An especially compelling application is an independent determination of the Hubble constant, $H_0$, using dark standard sirens, which associate GW signals with galaxy catalogues under the assumption that GW events are hosted by galaxies in the catalogue.

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
