Is the International Journal of Cosmology, Astronomy and Astrophysics (IJCAA) (https://madridge.org/journal-of-cosmology-astronomy-and-astrophysics) a respectable journal? I received from them an invitation, and it looks like a journal that could fit for something I would like to publish. However, I have a wary feeling. As far as I can see, it is not a predatory journal, but the articles look at times a bit amateurish. Does anyone know it? Any advice?
