Entity Framework ToListAsync() with Select()

I have the following ActionResult in my controller

public async Task<ActionResult> NewTickets()
{
    // Show tickets for all divisions a agent is in

    var user = "abcdefg";
    var company = "company1";

    var tickets = (from a in db2.Ticket
        join c in db2.Division on a.DivisionId equals c.DivisionId
        join dp in db2.DivisionParticipator on c.DivisionId equals dp.DivisionId
        where c.CompanyId == company.CompanyId && a.Status == "New" && dp.ApplicationUserId == user.Id
        select new
        {
            Id = a.Id,
            DivisionId = a.DivisionId,
            Name = a.Name,
            TicketDate = a.TicketDate,
            NewPosts = a.NewPosts,
            Status = a.Status,
            Type = a.Type
         })
         .ToList().Select(x => new Ticket
         {
             Id = x.Id,
             DivisionId = x.DivisionId,
             Name = x.Name,
             TicketDate = x.TicketDate,
             NewPosts = x.NewPosts,
             Status = x.Status,
             Type = x.Type
          });            

    return PartialView(tickets.ToList());
}

What i want to achieve is running this async, however if adding the ToListAsync()before Select()the Select() method becomes unavailable. The same goes for the return PartialView(tickets.ToList()).

I'm fairly new to working with async but reading about it's advantages I have been convering regular ActionResult methods with async ones. This has been going fine so far with easier LINQ-based queries. However for this ActionResult-method the query is a bit more advanced and the syntax/way to implement it seems to differ.

Any help to send me in the right direction would be greatly appreciated!
