“Image Processing from Astronomical Data”
Project – 3 (Lagoon Nebula)
07/02/2019, 4:10 am

This work is on “Lagoon Nebula” which is also known as “Messier 8 / M8 / NGC 6523 / RCW 146N and Gum 72.” It’s a giant interstellar cloud in the “Constellation Sagittarius.” It is classified as an emission nebula and as an H II region. This nebula is situated at 4000-6000 light-years away from the earth. 
This is the second time I worked on the nebula. ?

“Image Processing from Astronomical Data”
Project – 2 (Whirlpool Galaxy)
04/02/2019, 3:45 am

I wanted to work with one of my favorite galaxy which is “Whirlpool Galaxy.” I started work at midnight. After collecting the data, I started my work but I was startled after seeing the raw image. I thought I’ve downloaded the wrong data. Then I started my processing and after few minutes I got the galaxy which was invisible to me in the raw image. Finally, I finished my work at 3:45 am and it blew my mind. ???
The raw image and my processed image is given below. ?
Check that out and let me know how it is through your comment. ?
You can tell me about my blunders as well. ?

“Image Processing from Astronomical Data”
Project – 1
24/01/2020, 1:25 am

Okay, finally I’ve learned how to do astronomical image processing. ? 
Here is my very first work with a raw image. ?
I forgot the name of this image but this image data had taken by the prominent “Hubble Space Telescope.” ?

Research – 1 ( The Pleiades)

This research has done by the founder of the “Bangladesh Astronomy Research Center (BARC).”

Researcher:  Hasibul Hossain Rifat

 

Project-1: (Determine parallax of Pleiades)

Part – 1,2,3,4,5,6,7
29/12/2019, 3:30 am

As you guys know I was started working on the Pleiades which is a star cluster. I am working on its data. Here are the details about the work.

Part-1: (TGAS Cone Search):

Initially, I’ve selected the keyword in this cone search and then submitted the object name. Then I’ve chosen the data about pleaded set the parallax angle, radius and so on.

Part-2: (Proper Motion Plot):

In section 2, I’ve plotted the data into the plane lot option and got this graphically attached picture. In this picture, you might be seen some blue dots which are the comoving cluster.

Part- 3: (Parallax Histogram):

I’ve plotted those data into the parallax histogram section and in this picture, you can see it.

Part-4: (Exclude proper motion outliers):

This part is about to exclude proper motion outliers.

Part-5: (Cluster proper motion statistics):

This statistics table is showing us the “Cluster proper motion statistics” which has created in part-4. This cluster is the subset of part – 4. In these statistics, if you look at the “Mean and Stdev columns” then you will see the value clearly which is Pleiades parallax. The value I’ve got is
≈ 3.32915 ± 3.5 mas.

Part-6: (3D cluster positions):

In this part, we can see a 3D cluster position in the picture. It’s a sphere plot indeed.

Part-7: (Visualise proper motions):

Here I’ve visualized the proper potion of Pleiades.
