Can anyone make recommendations for Astrophysics ?
For various topics, I would look at:
Introduction to Cosmology by Ryden for cosmology at the undergraduate level.
Cosmology by Weinberg.
The Exoplanet Handbook by Perryman.
An Introduction to Modern Stellar Astrophysics by Carroll & Ostlie.
Particle Astrophysics by Perkins.
Modern Statistical Methods for Astronomy by Feigelson.
Statistics, Data Mining, and Machine Learning in Astronomy by Ivezic.
I can post more in other topics if anyone is interested.
