I am investigating whether firebase and angularfire are a good fit for my upcoming project.
One of the requirements are for users to be notified when the app is clos
Actually, today (May 19, 2016) Google rebranded GCM to Firebase Cloud Messaging and it now offers this cross platform service. Firebase also offers notifications.
These are the differences between these two services:

The answer is YES!
At 2017 Firebase published Cloud function. You can use a database trigger to send a push notification (using FCM) even when the app is closed.
I have created a tutorial for firebase cloud function and Xcode(iOS) if you're interested, for the javascript it's the same code: https://www.youtube.com/watch?v=jOJdlvMS6KA
Yes. This was not the case until recently, though.
Thanks to @libik for providing relevant documentation link:

Update 5/2016 :
on Google io 16 , Google announced FCM - Firebase cloud messaging service.
With the announced expansion of Firebase at Google I/O recently, we also introduced Firebase Cloud Messaging (FCM) and Firebase Notifications (FN). As a developer, there are lots of updates that you might be able to take advantage of.
see more at : https://developers.googleblog.com/2016/05/google-cloud-messaging-and-firebase.html
documentation : https://firebase.google.com/docs/cloud-messaging/#key_functions
As of today, the Google I/O has announced the new Firebase Cloud Messaging Service does now support sending push notifications. It integrates with Google Cloud Messaging to deliver messages upstream and downstream!
You can read more about it here:
And the Firebase Cloud Messaging reference is here:
Batch.com is offering a Push Notification service for Firebase

firebase is a storage. You wouldn't expect storage to do any actions.
For local notification generated by app when it is in the background you can constantly listen to changes in firebase and when the change occurs you can generate your push notification. In order to save the connection time since you are charged by concurrent connections, you can go offline and go online every 5 min for 20s. During this time firebase sdk connects to server, collects all the changes and runs all callbacks. You decide within your app what to do.
If you would like to enjoy remote push notification. You would need to setup a server listening to changes on firebase and talking to APNS which will push the notification to client's device.
