Ask HN: How do you follow the latest research papers in a certain field?

I want to be informed of the most recent research papers in some broad field (say AI, or particle physics). More specific sub-category is also fine. However, I don't want to get notified about every single paper, but preferably only the high impact ones.

Tried Google Scholar Alerts. It only supports keywords or author and gives me an unsorted list of papers. But what I really want is a list sorted by say citation, which is not supported.

Any tools or websites you find helpful to follow the latest developments?
