P71-013: Deducing physical parameters of TDEs through spectroscopic lag studies

P.I.: Panos Charalampopoulos

This is a SoftToO program using ALFOSC (Classification 4h total, follow-up of 2 TDEs, 6h each ) in Nordic Service or technical nights.

Requested setup:

  • Grism #4
  • Slit_1.0, Slit_1.3

Observing instructions:

When an observation is triggered, OBs will be made and submitted to the Queue:
  • In a sequencer window type cd ~/scripts/70-013/
  • Look for the most recent scripts with ls -lrt and execute them
  • Remember to update the OBs and send the SoftToO report

71-013 2025-04-04 00:55 SoftToO Targets observed AT2025eve, HD93521 ALId040081 - ALId040091 Clear skies and seeing around 1.0'' Observed
71-013 2025-04-08 00:00 SoftToO He3, AT2025chm ALId080066 - ALId080074 Tried to observe but thick clouds rolled in during exposures. Failed
71-013 2025-04-13 01:39 SoftToO HD93521, AT2025chm, AT2025eve ALId130054 - ALId130063, ALId130069, ALId130073 - ALId130077, ALId130092 - ALId130096 Targets observed with clear skies and seeing around 1". Different slits were used due to uncertainty about the seeing before starting the OB. For this reason, there are also standards using both slits. Observed
71-013 2025-04-17 00:54 SoftToO AT2025hbw, HD93521 ALId170075 - ALId170079, ALId170093 - ALId170097 Clear skies and seeing around 1.0'' Observed
71-013 2025-04-27 00:42 SoftToO AT2025htf ALId270069 - ALId270073 Clear skies and good seeing Observed
71-013 2025-04-28 00:00 SoftToO HD93521 ALId280097 - ALId280101 Only the standard star was observed due to the seeing limits. No time lost counted. Failed
71-013 2025-04-29 00:40 SoftToO AT2025eve ALId290064 - ALId290068 The seeing was way above 2.0". Observed
71-013 2025-05-02 00:53 SoftToO AT2025hbw ALIe020061 - ALIe020065 One target observed with clear skies and good seeing. For standard please use files ALIe020061 - ALIe020065. Observed
71-013 2025-05-03 00:35 SoftToO AT2025fry ALIe030104 - ALIe030108 One target observed with clear skies and around 1'' seeing. For standard please use ALIe030080 - ALIe030084 Observed
71-013 2025-05-04 00:38 SoftToO BD332642, AT2025izo ALIe040068 - ALIe040072, ALIe040089 - ALIe040093 Observed 1 target and a standard. During the target observation the guiding was quite bad likely due to passing clouds. This may have affected the data quality. If the data is not usable you may ask for the time back. Observed
71-013 2025-05-08 01:07 SoftToO AT2025chm ALIe080056 - ALIe080060 Observed with clear skies Observed
71-013 2025-05-19 00:20 SoftToO AT2017abr ALIe190056 - ALIe190060 First try aborted due to bad focus. Observed with sub-arc conditions, right after focusing the telescope. Clear skies. Observed

 

The above information is collected from the ToO/Mon reports that have been created by the observer.

Should any of the observations have been carried out using the OB system, you will find additional information HERE
