Nbody release 1.72 soon
I will be releasing a new version of the Nbody application within the next 24 hours. Its a minor change to our cost function, but an important one. Hopefully this version will converge to optimized values faster!

As always,
thank you for your continued support,

Database Maintenance
Hello Everyone.
I am Jeff Thompson and have been working on and off with MilkyWay@home since 2012, but I have been quiet recently.

For the next few months, on Tuesdays, we will be scheduling server maintenance.
We will post on the day threads for any issues that may arise.

This is a heads up.

Thank you for your continued support. 30 Aug 2018, 17:34:41 UTC · Comment

New MilkyWay@Home Developer
Hello all,

My name is Eric Mendelsohn, and I am a new developer working on the code for MilkyWay@Home. I am currently working on testing the impact of several parameters implicit within the N-body integrator used in MilkyWay@Home. I am also working on adding new gravitational potential models for the simulated bulge, disk, and halo of the Milky Way Galaxy. If you have any questions involving N-body, I will do my best to answer them as accurately as possible.

Thank you for your support! 21 Aug 2018, 17:42:13 UTC · Comment

New Separation Runs
Hey Everyone,

I put up a few new separation runs. You may notice that these have slightly different run times. The credit awarded should reflect the run time.

The run names are:

de_modfit_sim19fixed_bundle4_4s_NoContraintsWithDisk260_1
de_modfit_sim19fixed_bundle4_4s_NoContraintsWithDisk260_2
de_modfit_sim19fixed_bundle4_4s_NoContraintsWithDisk260_3
de_modfit_sim19fixed_bundle6_2s_NoContraintsWithDisk140_1
de_modfit_sim19fixed_bundle6_2s_NoContraintsWithDisk140_2
de_modfit_sim19fixed_bundle6_2s_NoContraintsWithDisk140_3

If you have any questions or issues, let me know.

PhD Thesis
Hey Everyone,

I just wanted to updated everyone on some of the current scientific work and results coming out of MilkyWay@home. These results can be found in my PhD thesis which I posted here.

The major result from this work is that we have mapped 7 stellar streams in the Milky Way halo. We believe two of these streams are likely to newly discovered streams.

These results would not have been possible without the contributions of the MilkyWay@home volunteers. Looking forward we hope to improve our mapping algorithms to find map new stellar streams and better fit those we have already found.

Thank you.

New nbody runs July 2
Hey All,

I just put up some new nbody runs. They will be the first to run off the new version (v170). I waited some time to put these up so the queue would clear out of the old workunits.

Please let me know if anyone encounters any issues with these runs.

As always, thank you for you continuing support,
