ON THE RELIABILITY OF MICROVARIABILITY TESTS IN QUASARS [PDF]

open access: yesThe Astronomical Journal, 2014
Microvariations probe the physics and internal structure of quasars. Unpredictability and small flux variations make this phenomenon elusive and difficult to detect. Variance based probes such as the C and F tests, or a combination of both, are popular methods to compare the light-curves of the quasar and a comparison star.

Micro-Contact in Southern Italy: Language Change in Southern Lazio under Pressure from Italian

open access: yesLanguages, 2022
This paper explores a novel case of contact-induced change due to micro-contact within Italy, where various Italo-Romance languages coexist (Standard Italian, Italiano Regionale ‘regional Italian’, and numerous local languages).

Dialectal variation in the expression of que in sí-que ‘yes that’ contexts across Spanish: The case of some Latin American Spanish varieties

open access: yesGlossa, 2020
This paper investigates dialectal microvariation across the Spanish-speaking world in terms of the presence/absence of que in sí-que contexts. The function of this construction is to signal the speaker’s commitment to the truth of the proposition.

Variation in Kimakunduchi and Standard Swahili:Insights from verbal morphosyntax

open access: yesLinguistique et Langues Africaines, 2022
This paper explores variation between Kimakunduchi and Standard Swahili with a focus on verbal morphosyntax. With several varieties of Swahili identified and described over the years, here we focus on the Kimakunduchi variety spoken in the south-east of ...

Microvariability in Seyfert Galaxies

open access: yesThe Astronomical Journal, 2003
We present the results of a search for microvariability in a sample of eight Seyfert galaxies. Microvariability (i.e., variations occurring on timescales of tens of minutes to hours) has been conclusively demonstrated to exist in the class of active galactic nuclei (AGNs) known as blazars. Its existence in other classes of AGNs is far less certain.

The Microvariable Activity of BL Lacertae [PDF]

open access: yesGalaxies, 2020
We report on seven nights of optical observation taken over a two-week period, and the resultant analysis of the intermediate-frequency peaked BL Lac object (IBL), BL Lac itself, at redshift z = 0.069. The microvariable behavior can be confirmed over the course of minutes for each night.

OPTICAL MICROVARIABILITY IN QUASARS: SPECTRAL VARIABILITY [PDF]

open access: yesThe Astrophysical Journal, 2010
We present a method that we developed to discern where the optical microvariability (OM) in quasars originates: in the accretion disk (related to thermal processes) or in the jet (related to non-thermal processes). Analyzing nearly simultaneous observations in three different optical bands of continuum emission, we are able to determine the origin of ...

Variation in differential object marking: On some differences between Spanish and Romanian

open access: yesOpen Linguistics, 2020
Although differential object marking (DOM) has been studied from a multitude of perspectives, research into the types of variation it allows in closely related languages is still needed.

Dative Microvariation in African Varieties of Portuguese

open access: yesJournal of Portuguese Linguistics, 2022
In this paper we compare dative ditransitive structures in nativized and nativizing urban varieties of Portuguese spoken in Angola, Mozambique, and São Tomé and Príncipe, using a corpus-based approach. It is shown that the expression
