i live in an apartment that was recently put in Notice of Lis Pendens. What should I do? The landlord is now deceased. I dont know who owns the place

To whom do you pay rent?  If no one, you will be evicted.  Call the foreclosing attorney to find out the owner.

If you were served with a notice of lis pendens, that will tell you the name of the owner. You have many options. The safest one is to find a new place to live ASAP. You can also try to negotiate with the bank and the co-op to pay them directly and rent the apartment on a month to month basis until the foreclosure takes place, or buy the apartment. Or if you're up for a little risk and don't mind if your credit score takes a beating, stop paying everyone and see how long you can stay there. I've seen subtenants live rent-free for years in your situation. Of course the co-op/condo and/or the bank could get a money judgment against you, but that's unlikely and even if they do it's unlikely they'll enforce it. Good luck.
