I am curious to any research or theories to where children develop their intellectual curiosity. I want to be able to do everything I can to help nurture this.
You can encourage curiosity - for most of the early formative years you are your children's best role model, so they will take on habits from you.
Now, you can't just drag them along to everything you want to do - that could very easily make them switch off - it mustn't be a chore for them. Be excited. Be enthusiastic. Treat things as new. Don't show - but show how to find out things.
It can be staggeringly exciting for you as a parent to nurture and see them develop into inquisitive individuals.
This article has some interesting insights to why humans are curious, but if by intellectual curiosity you mean academic curiosity, I think everyone has a bit of it in them; it's just a matter of allowing them to choose what they want to discover.
For example, for someone who wants to program video games, physics (and in turn calculus), art, and sometimes anatomy/biology to understand how to create realistic characters are required. While video games might not seem very intellectual, most academic subjects are related to other things (in my example physics, calculus, art, and anatomy/biology are related to video game programming).
I think the only thing that needs to be done to nurture curiosity is to make sure resources are available to your child, which could mean anything from going to the library, to showing him/her how to find answers to questions on the internet or through books, or going to a museum every now and then. Allowing the child to explore what they want when they want to is what's most important because that's what will cause them to retain information.
The Sudbury Valley model of schooling and unschooling may also be of interest of you're curious about nurturing a child's intellectual curiosity.

A child's curiosity starts occurring predominantly from around the age of 5 or 6 and starts decreasing exponentially with increase in knowledge. I mean, the curiosity behavior depends on various factors like,
At the start (around 5 years), they're curious of everything. Like when you're walking on the road, they wonder about everything and start bugging, "How does this car go fast?", "How does that plane go so high?", "What is this one?, that one?". Most probably, Children don't care of nature, etc (very rare smart cases will ask about everything). Their questions mostly arise in technology or mechanics.
Whenever they ask a question to you, just try to explain them. If you can't (for example, if he asks "What is the temperature of sun?" - a question arriving around 8 years), ask your friends, take him to a planetarium or some astronomical park (like that), hang along with him and find the answer and explain it to him (even though it takes a month)..!
This sort of searching may sometimes make them think, "Our mom/dad will definitely answer whatever we ask them..." as they become mature. This is one kind of encouragement which I could recall.
Around 10, (they get to know the answers to most of the things via interaction in schools) - In that duration, the questions they arouse on parents would be somewhat low in quantity.
A sidenote: As a parent, you must be curious in knowing "What his interested field might be?" between the age of 5 and 10 (I really bet that it wouldn't be too hard to find out). But, finding it would be too late after he has crossed the barrier. Coz around 10-15, there would some fluctuations in his field (teenage) and hence your investigation would be difficult to succeed. Once he has crossed 16, you don't even need to answer him. Coz, he/she might be solving the
One thing I've learned from my past. A quote I'd like to plagiarize from my professor's speech. A quote which I won't forget..!
"This education system is awful. We are always curious in "How to learn it?" and not "Why to learn this?" My belief: Better focusing the children in the WHY? part (by parents) may nurture his curiosity.
