The limited role of galaxy mergers in driving stellar mass growth over cosmic time
(2017-11-21)A key unresolved question is the role that galaxy mergers play in driving stellar mass growth over cosmic time. Recent observational work hints at the possibility that the overall contribution of `major' mergers (mass ... -
Limits of noise and confusion in the MWA GLEAM year 1 survey
(2015-10-20)The GaLactic and Extragalactic All-sky MWA survey (GLEAM) is a new relatively low resolution, contiguous 72-231 MHz survey of the entire sky south of declination +25 deg. In this paper, we outline one approach to determine ... -
The limits of understanding and the understanding of limits : David Hume’s mathematical sources
(Springer Nature, 2023-05-12)David Hume devoted a long section of his Treatise of Human Nature to an attempt to refute the indivisibility of space and time. In his later Enquiry Concerning Human Understanding, he ridiculed the doctrine of infinitesimals ... -
Limits on radioactive powered emission associated with a short-hard GRB 070724A in a star-forming galaxy
(2010-05-11)We present results of an extensive observing campaign of the short-duration, hard spectrum gamma-ray burst (GRB) 070724A, aimed at detecting the radioactively powered emission that might follow from a binary merger or ... -
Limits to competition and regulation in privatized electricity markets
(2009)Privatization of electricity has been extensive both in the developed and the developing world. Failures in various areas have led to the emergence of a new consensus which regards competitive pressures and regulation as ... -
The limits to participatory planning : A reply to Adaman and Devine
(2005)Fikret Adaman and Pat Devine (2001) responded to an article in which I criticized proposals by socialists to give markets marginal role (Hodgson, 1998). This present essay continues the debate, raises some additional issues ... -
Line-driven disc wind models with an improved line force
(1999)We describe an efficient method of calculating the radiation pressure due to spectral lines, including all the terms in the velocity gradient tensor. We apply this method to calculate the two-dimensional, time-dependent ... -
Linear analysis of genetic algorithms
(1998)We represent simple and fitness-scaled genetic algorithms by Markov chains on probability distributions over the set of all possible populations of a fixed finite size. Analysis of this formulation yields new insight into ... -
The linear bias of radio galaxies at z~0.3 via cosmic microwave background lensing
(2019-02-26)We present a new measurement of the linear bias of radio loud active galactic nuclei (RLAGN) at $z\approx0.3$ and $L_{\rm 1.4GHz}>10^{23}\,{\rm W\,Hz^{-1}}$ selected from the Best & Heckman (2012) sample, made by ... -
Linear Line Polarimetry Modelling of Pre-main Sequence Stars
(Astronomical Society of the Pacific, 2005)We present emission line polarimetry data and modelling relevant to the circumstellar geometry and kinematics around pre-main sequence stars. For a sample of both Herbig Ae/Be stars and T Tauri stars, we find that most ... -
Linear Permanent Magnet Vernier Generators for Wave Energy Applications: Analysis, Challenges, and Opportunities
(2022-09-01)Harvesting energy from waves as a substantial resource of renewable energy has attracted much attention in recent years. Linear permanent magnet vernier generators (LPMVGs) have been widely adopted in wave energy applications ... -
The linear polarisation of southern bright stars measured at the parts-per-million level
(2016-01-11)We report observations of the linear polarisation of a sample of 50 nearby southern bright stars measured to a median sensitivity of ~4.4 x 10^{-6}. We find larger polarisations and more highly polarised stars than in the ...
