Announcing Hotwired 5 to be hosted at Villanova

May
05



Hot-wiring the Transient Universe is a series of meetings to explore the opportunities and challenges of massively parallel time domain surveys coupled with rapid coordinated multi-wavelength follow-up observations. The interdisciplinary agenda include future and ongoing science investigations, information infrastructure for publishing observations in real time, novel data science to classify events, and systems to optimize follow-up campaigns. Time domain astronomy is at the fore of modern astrophysics and crosses fields from solar physics and solar system objects, through stellar variability, to explosive phenomena at galactic and cosmological distances. Recent rapid progress by instruments in space and on the ground has been toward a continuous record of the electromagnetic sky with ever increasing coverage, sensitivity, and temporal resolution. With the advent of gravitational wave and neutrino observatories, we are witnessing the birth of multi-messenger astronomy. More information on Hotwired 5 can be found here.

Water? Who needs water if you got super-critical CO2!

Nov
24

A recent study recapped in this story hints at a possibility of super-critical carbon dioxide playing a role of water. In short, super-critical CO2 is a special aggregate state of CO2 at high temperatures and high pressures where it attains fluid properties while still in gaseous form, and becomes particularly well suited for organic compound hosting. A good read for all of you interested in possibilities of life outside our planet!

Nebular theory tested before our eyes!

Nov
06

In the Life in the Universe course, we talk about the Nebular theory and how it explains the formation of planets. Today, the Atacama Large Millimeter Array (ALMA) team unveiled an image of a planet-forming disk around a young star HL Tauri. Hopefully that provides further credibility to my students when thinking of the origin of our own solar system. For more details see the official press release.

The Learning Myth

Aug
29

I hate to come across righteous or patronizing, but I think this needs to be said. Somewhat frequently I am reminded by the students that I am too demanding and, especially for the Arts majors in science, that the students are struggling beyond what is "expected". My usual rhetoric is to say that my criteria are a reflection of respect: I believe in my students, given that they are the intellectual centerfold of our future, and the more highly I regard them, the more I expect of them. Here is another take at making the same point, from a completely different perspective (and my hands are clean on this one): The Learning Myth.

Last week of sabbatical...

Aug
14

I have to say that it was a great sabbatical! In a nutshell, 3 papers written, one of them accepted, two about to be submitted, both to Nature; met great new friends and colleagues, and learned a bit of asteroseismology. Got to visit Slovenia 3 times, the Netherlands and Malta, not to mention all the attractions UK has to offer! My favorites were the highlands of Scottland, the Lake District and, inevitably, London. A wine store in Clitheroe will also remain etched in my mind, and a fabulous Scottish accent.

Swapping hard drives across nodes ... baaaad idea...

Apr
19

I lost sleep over this event so I figured I'd put it in writing now that most of it is over...

Prologue.

We recently purchased two new 48-core nodes for our astronomy cluster here at Villanova. I decided to bite the bullet and designate one of the two new nodes to be the server for the whole cluster, and the other be just the regular node. I installed the basic system, hardened it, installed all the relevant software and then gone on to install... gulp... IDL.

Andrej vs. Plastic Bag

Feb
10

This is a brief recount of last night's events that I decided to write up in the hope that I'll think twice before I decide to do something silly like this. ;)

Prologue. I have been struggling with this nasty cold for a few days now. It's not one of those debilitating colds, rather it's one of those persistent colds where every morning your throat feels like you've been chewing on razorblades.
