A historical perspective on the concept of galaxy size
Nushkia Chamba
A brief narrative on how the effective radius and isophotal diameters were accepted as galaxy size measures is presented. Evidence suggests that these parameters were defined only…
Optimising and comparing source extraction tools using objective segmentation quality criteria
Caroline Haigh, Nushkia Chamba, Aku Venhola +4
With the growth of the scale, depth, and resolution of astronomical imaging surveys, there is an increased need for highly accurate automated detection and extraction of astronomic…
A physically motivated definition for the size of galaxies in an era of ultra-deep imaging
Ignacio Trujillo, Nushkia Chamba, Johan H. Knapen
Present-day multi-wavelength deep imaging surveys allow to characterise the outskirts of galaxies with unprecedented precision. Taking advantage of this situation, we define a new…
Are ultra-diffuse galaxies Milky Way-sized?
Nushkia Chamba, Ignacio Trujillo, Johan H. Knapen
Now almost 70 years since its introduction, the effective or half-light radius has become a very popular choice for characterising galaxy size. However, the effective radius measur…
