Editing Centaurus A (section)

==Distance==
Distance estimates to Centaurus A established since the 1980s typically range between 3–5 Mpc.<ref name="tonryetal2001"/><ref name="ned-dist"/><ref name=ferrarese07/><ref name=majaess10/><ref name=harris10/><ref name=rejkuba04/> [[Classical Cepheids]] discovered in the heavily obscured dust lane of Centaurus A yield a distance between ~3–3.5 Mpc, depending on the nature of the extinction law adopted and other considerations.<ref name=ferrarese07>{{cite journal | author = Ferrarese Laura | display-authors = 4 | author2 = Mould Jeremy R. | author3 = Stetson Peter B. | author4 = Tonry John L. | author5 = Blakeslee John P. | author6 = Ajhar Edward A. | date =2007 | title = The Discovery of Cepheids and a Distance to NGC 5128 | doi = 10.1086/506612 | bibcode=2007ApJ...654..186F | journal = Astrophysical Journal | volume = 654 | issue = 1| pages = 186–218 |arxiv = astro-ph/0605707 | s2cid = 17895798 }}</ref><ref name=majaess10>{{cite journal|bibcode=2010AcA....60..121M|author1=Majaess, D.|date=2010|pages=121|volume=60 |issue=2|title=The Cepheids of Centaurus A (NGC 5128) and Implications for H0 |journal=Acta Astronomica|arxiv = 1006.2458 }}</ref> [[Mira variable]]s<ref name=rejkuba04>{{cite journal |bibcode=2004A&A...413..903R |title=The distance to the giant elliptical galaxy NGC 5128 |journal=Astronomy and Astrophysics|arxiv = astro-ph/0310639 |doi = 10.1051/0004-6361:20034031 |date=2004 |last1=Rejkuba |first1=M. |volume=413 |issue=3 |pages=903–912 |s2cid=15938660 }}</ref> and [[Type II Cepheid]]s<ref name=ferrarese07/><ref name=majaess10/> were also discovered in Centaurus A, the latter being rarely detected beyond the [[Local Group]].<ref name=majaess09>{{cite journal |author1=Majaess, D. |bibcode=2009AcA....59..403M |date=2009 |author2=Turner, D. |page=403 |author3=Lane, D. |title=Type II Cepheids as Extragalactic Distance Candles |volume=59 |issue=4 |journal=Acta Astronomica|arxiv = 0909.0181 }}</ref> The distance to Centaurus A established from several indicators such as [[Mira variable]]s and [[planetary nebula]]e favour a more distant value of ~3.8 Mpc.<ref name=harris10b>{{cite journal |bibcode=2010PASA...27..475H |author1=Harris, Gretchen L.
